When lakes and ponds exhibit problems like algae, aquatic weeds, bad odors, cloudiness, or muck development, it can prevent us from benefiting from the connection with nature that our waterbodies provide. Aquatic experts use a variety of techniques to diagnose the underlying issue. One of the most important tools is water quality testing. By analyzing water samples in a professional laboratory, scientists can identify the chemical imbalances that are preventing you from enjoying your waterbody to the fullest. Once data is collected, experts will implement tailored management solutions to restore the balance and beauty of the ecosystem. One natural and highly effective solution is Alum.
Alum has been a long-standing tool in our toolbox of lake and pond management solutions—and is a particular favorite of professionals who strive to use only sustainable maintenance practices. Alum (also known as Aluminum Sulfate) is used in a wide array of industries and applications such as drinking water management and wastewater treatments. In the lake and pond management industry, Alum is used to reset the chemical balance of aquatic environments to improve water quality. When water quality is enhanced, it creates an environment that is less hospitable to algae, nuisance weeds, and toxic cyanobacteria.
There is no one-size-fits-all approach to lake and pond management. This means that Alum may not be the right solution for each and every waterbody. Water quality tests help us understand the problems occurring under the surface and make this decision. Most often, Alum is deployed when water quality tests reveal unusually high levels of nutrients like Phosphorus, which is typically the root cause of undesirable organic growth.
Alum is applied to lakes and ponds as a white, powdery substance. As the Alum mixes into the water column, it binds with free-reactive nutrients, creating a cloudy trail behind the boat or a specially-designed application barge. After a short period of time, the particles sink to the bottom where they will remain inactive. Alum is considered very safe when applied by a professional and provides fast-acting results that can last for years. Almost immediately after an application is complete, the water column will become more clear. Over the course of days and weeks, the water quality improves.
Once the waterbody is restored to more balanced conditions, it’s important to prevent future nutrient loading by addressing the external sources of Phosphorus. Trash, pet waste, fertilizers, motor oil, sewage, and yard waste are often to blame. They can flow into lakes and ponds during rainstorms. Rainfall and weather events can also damage the shoreline, causing nutrient-rich soil and plant matter to crumble into the water. Stakeholders can slow this problem by establishing a robust vegetative buffer around the shoreline. Professionals recommend using native plants that grow approximately 18 inches high and develop complex root systems to naturally hold soil in place. If shorelines have sustained significant damage over the years, it may be necessary to completely rebuild them using bioengineered mesh technology that can be seeded with the grass and buffer plants following installation.
Alum is not the only natural substance that removes nutrients in the water column. Solutions like Phoslock and EuroSORB work similarly to target Phosphorus.
Phoslock is a lanthanum-modified clay that binds with excess phosphorus, chemically changing its composition so that they can no longer support weeds and algae. EutroSORB, on the other hand, is a filtration technology that captures nutrients in the water column. It is particularly effective in waterbodies with significant movement and mixing, such as stormwater ponds, streams, and canals. Once the filter is fully saturated with phosphorus, it is pulled from the water for disposal. In some cases, experts may also choose to use an aqueous form of EutroSORB that can be poured or sprayed on the surface, or applied via subsurface injection.
Your lake and pond management professional may consider a number of factors when choosing which of these three nutrient remediation products to implement. These may include your waterbody’s size, location, use, pH, dissolved oxygen concentration, muck level, and degree of water movement.
The well-being of our aquatic environments reflects our own. Science shows that humans are happier, healthier, and more relaxed when spending time around beautiful water. Nutrients are the building blocks that help create these amazing ecosystems that delight us, but it’s necessary to maintain them at balanced levels as nature intended. Alum is one of many eco-friendly tools employed through an annual maintenance program. Like most solutions, it is most effective when used proactively. Click to learn more about the benefits of Alum and the important role it plays in a year-round management plan.

Wetlands play an extremely important role in the ecosystem, particularly in Florida. In addition to their cultural relevance, they are a central feature that is home to thousands of incredible species. Preserving them is not only beneficial to the natural ecosystem, it benefits our communities in many ways.
Simply put, wetlands are lands that transition between terrestrial and aquatic environments. More specifically, wetlands contain soils that are inundated long enough to support the growth and reproduction of diverse vegetation.
The plants that grow in wetlands have adapted in a way that lets them survive in the hydric or wet soils. Swamps, marshes, bayheads, bogs, cypress domes and strands, sloughs, wet prairies, riverine swamps, mangrove swamps, and other similar areas meet the criteria of wetlands.
There are wetlands on every continent. Although the Everglades are the most well-known wetlands in Florida, there are many other wetland areas throughout the state. A healthy wetland supports a wide range of wildlife such as birds, amphibians, crustaceans, fish, and reptiles.
The aquatic freshwater and marine life of Florida depend on wetlands for feeding grounds and nurseries for their young. In addition, wetlands also offer outstanding recreational opportunities for fishing, boating, bird watching, and photography – to name just a few. Unfortunately, wetlands face many threats:
Wetlands originally covered approximately 60% of the state’s land, but over time, wetlands have been reduced by urban development to less than half of that amount. Human activities are arguably the greatest threat to wetlands due to the draining of these lands for agriculture or development. Historically, wetlands were considered wastelands and were drained and cleared of vegetation without a second thought to make way for homes, roads, and shopping centers.
Loss of wetlands habitat not only affects animals and plants, but it also diminishes the water supply for the human population, since wetlands hold, filter, and slowly release immense amounts of rainwater into the aquifers that serve as central and south Florida’s only source of freshwater.
Like all ecosystems, the survival of the plants and animal species that live in wetlands depend on a delicately balanced environment. When non-native species are brought in, either on purpose or accidentally, it can unbalance the existing system. Invasive species compete with native species for limited resources. When native species start to die off as a result of competition with an invasive species, the food chain of the ecosystem is disrupted.
For example, some wetlands are being overrun by water hyacinth. This plant is held in check in its native environment, but in North American habitats, it spreads at an alarming rate. Similarly, Burmese pythons were brought into the country as pets and released into local wetlands where they grow too big to be sufficiently supported by their environment. These large snakes thrive in wetlands like the Everglades and threaten the survival of endangered species.
Wetlands work as natural water filtration units. Polluted water washes into the wetlands and is purified as it flows through and out of the wetlands. The pollutants either settle to the bottom of the wetlands or are used by the plants growing in these habitats. But if the concentration of pollutants reaches and then crosses the saturation level, and toxic contaminants continue entering the wetlands, the plants and animals struggle to survive.
In addition, wetlands are often used as dumping grounds for industrial and household waste and sewage. High pollution rates in wetlands kill off fish, wildlife, and plants, destroying the habitat.
Like other ecosystems and habitats, wetlands are also affected by alterations to the environment caused by climate change. Sea-level rise caused by warming temperature is submerging or drowning wetlands, while extreme weather such as drought is drying them out. Higher water levels and lower water levels are caused by the various effects of climate change.
The construction of dams that alter the natural flow of a river also has a huge impact on the environment where it is built. Altering the flow of a river disturbs the ecosystems that depend on that river. Wetlands like swamps or marshes suffer from a higher or lower flow of water when a dam is built. Dams can permanently damage wetland ecosystems.
Wetlands are productive ecosystems that provide environmental benefits to the areas that surround them. Waterfowl and migratory birds, and other wildlife make wetlands their home. As important as that is, these dynamic natural systems provide services such as removing harmful chemicals and excess nutrients from storm runoff, recharging aquifers used for drinking water and irrigation, and protecting communities from coastal storm surges and flooding.
Coastal wetlands and estuaries support diverse habitats that provide shelter and food for recreational and commercial fisheries, which in turn contribute to local economies. People are often drawn to wetlands for outdoor recreation and wellness. Outdoor recreation is important for the health of the population as well as the economy.
These important functions make wetlands a vital part of our environment. Maintaining and improving the health of wetlands support plants, animals, and people. Here are five ways to help conserve Florida’s wetlands:
Improve the health of wetlands by planting buffer strips of native plants near and around water resources. These buffers can help filter out fertilizers and pollutants before they enter the water and cause environmental imbalances. They also help hold soil in place for lasting structure and aesthetic appeal.
Non-native plants that quickly become invasive can have devastating consequences on wetlands. They choke out native species and change the function of the wetlands. Likewise, invasive animals compete with native wildlife for food and habitat, creating a negative cycle within the food web. Monitor the area and report the presence of any invasive species immediately.
Avoid using pesticides and fertilizers for lawn or garden care. These chemicals can harm aquatic species and wildlife by negatively affecting water quality and encouraging invasive plant growth. When absolutely necessary, use organic products in place of chemicals.
Animal waste can wreak havoc on wetlands and their population. Make sure that pet waste is kept out of wetlands by keeping dogs fenced in or leashed, and keeping your cats inside as much as possible. When walking pets or playing outdoors, always pick up and properly dispose of any waste.
Wetlands are amazing ecosystems containing a complex web of plants, animals, fish, and organisms. Change is always occurring, so it’s important to stay informed about the health of the environment. Freshwater management professionals are experienced in monitoring and maintenance solutions aimed at preserving the health and beauty of these habitats. Consider implementing an annual management program to preserve wetlands in your area.
Florida is known for its magnificent wetlands, but that doesn’t mean they will be around forever. Through urban development, invasive species introduction, pollution, and other factors, humans have expedited the deterioration of wetland areas. We should each play an active role in the protection of these unique aquatic ecosystems so that we can enjoy, admire, and benefit from them for as long as possible.

Humans have a powerful connection to water. Learn how consistent lake management can help create happier, healthier communities.
It is scientifically proven that being around healthy, beautiful water can reduce anxiety and stress, boost creativity and improve our overall wellness. This is one of the many reasons why our community’s freshwater resources should be maintained with diligence. Discover how to best manage water quality issues and create a more relaxing, enjoyable space you, your loved ones, and your community can enjoy.
Lakes, rivers, beaches, and even swimming pools have beneficial effects on the well-being of visitors that are hard to define. Water is not only essential for our survival, it has a profoundly relaxing and refreshing impact on people’s mental health and happiness. Human beings will always be inextricably connected to water physically, mentally, and spiritually. This helps explain why communities near large water systems are common vacation destinations and highly desirable places for residential communities. It also underscores the importance of preserving our precious aquatic resources.
Maintaining balanced aquatic ecosystems is more important than ever as water scarcity, eutrophication, drought, and increasing demand continue to cause depletion and degradation of water quality worldwide. Water pollution can lead to Harmful Algal Blooms, toxicity, nuisance and invasive aquatic weed growth, bad odors, and taste issues in drinking water reservoirs – among many other issues. These types of water quality challenges can lead to diminished property values and will undoubtedly have a negative effect on swimming, boating, fishing, wildlife watching, and overall enjoyment of nature.
In many areas, it’s common for water quality problems to shut down lakes and beaches throughout the summer, but few people are cognizant of why these problems occur and how significantly they can threaten our innate connection with the water. Assessing and addressing issues with water quality requires the experience and knowledge of experts who focus on optimizing all the benefits that balanced water can provide.
Preserving and enhancing water quality calls for successful proactive management with long-term results in mind. Lake and pond management is a science and taking all variables into account is the only way to address water quality issues at their root causes. Aquatic biologists pay close attention to detail and consider the entire aquatic ecosystem when collecting sound physical, chemical, and biological data.
Water quality assessments are a common starting point to uncover this important information and identify potential nutrient imbalances, pollutants, watershed inputs, algal populations, or other problems. With every visit to your waterbody, aquatic biologists can learn more from each new water sample. This data creates a basis for management recommendations and informs the use of eco-friendly tools and advanced technologies.
Depending on the challenges your waterbody faces, it may require a combination of solutions. Fountains and submersed aerators are excellent at increasing healthy dissolved oxygen levels in the water while circulating different areas of the water column. Likewise, new aeration solutions like side stream supersaturation are changing the game by making it possible to directly inject oxygen into the water to correct deficiencies, eliminate bottom muck, and potentially end reliance on herbicides.
In the event that herbicides are required to achieve lasting aquatic weed control, advanced drone technology is now available to efficiently and precisely target affected areas. Drones also aid in surveillance, making it easier than ever to identify problems such as eroded shorelines, which can be rebuilt with innovative mesh technologies that integrate seamlessly into the landscape for lasting stabilization. These efforts are often paired with sediment removal strategies like hydro-raking and the application of nutrient management products that prevent future algae and aquatic weed growth. These steps can be further supported with the introduction of deep-rooted native vegetation, which form beneficial shoreline buffers that prevent undesirable nutrients and pollutants from entering the water.
These solutions provide immediate benefits, but they are not permanent. Lakes and ponds require year-round care for long-term success. An annual management program comprehensively supports aquatic ecosystems with many of these solutions and others that nurture waterbody health and functionality. When an annual plan is uniquely tailored to the individual characteristics of your waterbody, you can maximize the many physical, mental, and spiritual benefits of time spent in and around the water.

Florida is famous for its beautiful wetlands, but these natural treasures are threatened by hundreds of different factors, from the composition of bottom sediments to features in the surrounding landscape. The space where these environments meet provides valuable insight about the health and diversity of an aquatic ecosystem. This unique area is called the littoral zone.
The littoral zone is the down-sloping shelf of a pond or lake. This is the area that stretches from the high-water mark to the shore and into the area where sunlight penetrates through to the sediments at the bottom of a waterbody. Although the exact definition of littoral zone can change depending on the waterbody, it is generally considered the shallow area close to the shore in both saltwater and freshwater environments.
When healthy, the littoral zone looks like a miniature wetland. The beneficial plants that grow here often feature purple, white, yellow, or blue flowers that usually bloom all year long in Florida’s climates. These plants may include Golden Canna, Pickerelweed, Southern Blue Flag Iris, Fragrant Water Lily, and Florida Swamp-Lily.
The littoral zone or littoral shelf supports a large number of native plants and aquatic life. Because Florida’s aquatic species are so diverse, some plants can survive partially or completely submerged while others do just fine floating on the water’s surface. Waterbodies that support a wide variety of native plant species tend to provide more nutrients to the native wildlife that are key to maintaining cover and habitat. In addition to supplying food to ponds and lake fish, local plants help maintain balanced levels of oxygen and other key elements.
In addition to protecting the health of lakes or ponds, the littoral zone can enhance the aesthetic appeal of any Florida waterbody. When filled with thriving plants and wildlife, a well-tended littoral zone adds value to the shoreline and even the surrounding property.
A littoral zone helps improve water quality by fostering beneficial species that consume the excess nutrients that contribute to nuisance algae and invasive aquatic weed growth. Additionally, when located near a flow structure, the littoral shelf helps filter out the minerals and nutrients in water before it leaves the lake or pond. This improved water quality has the added benefit of keeping mosquitos at bay and reducing foul odors exuding from the water.
Littoral shelves also help maintain the shoreline and prevent erosion. The native plant roots hold the soil and make the banks more stable and durable, which in turn helps reduce the need for extensive restoration or dredging projects in the future.
Because the littoral zone transitions from dry land to the aquatic environment, it responds to natural and human influences and activities in the land ecosystem as well as the aquatic one. And because it is important for many industrial and recreational purposes, the littoral shelf is often drastically affected by human activities that amplify algal and weed growth, nutrient loading, overgrowth of invasive species as well as cause acidification and fluctuations in the water level. This underscores the importance of the littoral zone and littoral shelf maintenance for the health of lakes and ponds.
When properly established and managed, the littoral zone is less likely to require herbicide or algaecide applications. Recurring proactive management strategies such as nutrient remediation, biological bacteria applications, water quality testing, aeration, Oxygen Saturation Technology (OST), and other sustainable solutions can have a lasting positive impact in Florida’s delicate aquatic environments. A SOL Pro Annual Management program will help any property owner prolong the balance and beauty of their lake or pond’s littoral zone.
During the summer, we all look forward to recreational activities on local lakes and ponds; however, sometimes our plans are canceled due to unsightly, smelly, harmful algal blooms. Knowing a little about how HABs form can help us understand their health effects, ways to identify them, and strategies to prevent them.
Algae are a natural feature in many aquatic ecosystems. Most lakes have some algae growth on a regular basis, especially during the warm summer months, but it is crucial to stay on top of the algae development since blooms can happen quickly – before you know it, there are ugly floating mats on the lake’s surface. Likewise, certain species like cyanobacteria (also referred to as blue-green algae) can create concerning conditions by releasing dangerous toxins into the water.
Here are some signs that a bloom may be harmful:
Each bloom’s toxicity can vary and it’s hard to predict how dangerous a bloom will be as its toxicity changes daily. If the lake on your property looks like it may be developing dangerous levels of algae growth, take immediate steps. Not all blooms are toxic, and the only way to be sure that a bloom may become toxic is through laboratory testing. However, it can take a few days to collect and test samples, and by then, it may be too late.
Most often, harmful and toxic algal blooms occur because a lake or pond is not healthy. The lake may have an excess nutrient load due to the presence of too much phosphorus and nitrogen. When there are too many of these nutrients in the lake water, algae can overgrow or bloom.
A waterbody’s health can change year over year, depending on the weather and other factors in its surrounding environment. This is why a lake that was seemingly healthy suddenly experiences a bloom. This doesn’t necessarily mean the lake is destined for poor health, but it does indicate that there are imbalances that must be addressed.
Conditions that may change lake health and cause a harmful algal bloom include:
The toxins produced by harmful algal blooms can cause serious health impacts to pets, people, wildlife, and livestock. These health effects can range from skin irritation and rashes, gastrointestinal illnesses, neurological problems, and even death.
Once algae have overgrown enough to cause a large bloom, management can be challenging. Prevention is the best way to ensure harmful algal blooms don’t occur. Association boards and community managers can help prevent or minimize the risk of harmful algal blooms by taking the following steps:
To eliminate algae, the best course of action is to contact a freshwater management professional who can monitor and maintain balanced water quality and advise and apply appropriate management solutions. These professionals will ensure that the lake or pond’s water is clean and healthy and that the levels of algae remain at beneficial, manageable levels.

First of all, it is not healthy for them as they become dependent on people for food. The best food for ducks is what they eat naturally— algae, insects and a variety of plants which are abundant in our subtropical climate. Humans most often feed them bread and similar items. These have no nutritional value for the duck. Additionally, feeding by humans makes the ducks reliant on such hand-outs, too lazy to continue foraging for their natural dietary items and uneaten “human” food will rot quickly in warm weather.
Second, feeding ducks encourages them to use the neighborhood as their bathroom, leaving droppings on patios, sidewalks and porches. As a result, controversies frequently arise between residents who enjoy the birds and residents who consider them a nuisance. Even duck lovers have complained about the problem of duck droppings on the lawns, drive-ways, patios, and even in their swimming pools. This is not healthy for people, particularly for the children playing in these areas. Wild ducks can spread disease to humans. When small children, the elderly and persons with immune system problems directly handle newly-hatched chicks, they may be exposed to salmonella. Muscovies can also transmit disease to wild waterfowl. All confirmed outbreaks of DVE, also known as duck plague (a sometimes-devastating viral infection) in wild waterfowl have been linked to domestic ducks. Fowl cholera is another serious disease that is transmittable between domestic and wild waterfowl. Although we have had no major outbreaks reported yet in Florida, the potential for Muscovies to spread this disease to wild waterfowl is a biological concern.
DON’T: Feed ducks bread or junk food. Foods like bread and crackers have no nutritional value to ducks and can cause malnutrition and painful deformities if consumed too much.
DON’T: Leave uneaten food lying around. Leftover food in the water can rot and cause deadly algae blooms that affect local wildlife.
DON’T: Try to pet wild ducks. They may not appreciate your efforts!
Keep a respectful distance and remain nonthreatening, especially to ducklings who may become stressed or injured more easily.

Shoreline erosion can be detrimental to the health of your waterbody as well as the safety and value of your property.
Most communities throughout Florida utilize lakes and ponds to enhance the aesthetics of homes and golf courses, as well as support recreational opportunities such as boating and fishing for residents. The majority of these waterbodies were man-made for practical and functional purposes, such as capturing stormwater to prevent flooding or storing water to use for irrigation. Unfortunately, natural erosion of the shoreline is inevitable. It is an issue that only gets worse over time and should be addressed immediately, followed by consistent monitoring.
Shoreline erosion is a serious issue for waterbodies of all sizes and uses. It can degrade shoreline property, increase the risk of flooding, interfere with recreational opportunities, and threaten aesthetic appeal. In many cases, the deep cracks and gullies that appear can expose sprinkler systems, drainage pipes, and electrical cables, leading to costly repairs. Likewise, due to the effects of erosion, lakefront homeowners may find that their property decreases in size and value over time.
When slopes become too steep, the shoreline can also become unsafe for residents, children, pets, and recreationers. Steep slopes increase the risk of someone falling into the lake and being injured. The steepness of the slope can also make it hard for someone to get out of the lake when they fall in. This can pose a significant liability for HOAs, golf courses, commercial properties, and private homeowners.
Erosion has many natural causes:
The presence of nuisance fish and wildlife such as invasive armored catfish and otters that burrow into banks and cause them to collapse
Although these causes are natural, human activities can also increase the rate of erosion:
Despite the best efforts of HOAs, golf course superintendents, and municipalities, all waterbodies will experience erosion to some degree. However, there are many strategies to control or mitigate erosion.
Planting deep-rooted grasses and flowering vegetation will help retain, hold and stabilize the soil. This ground cover also helps to deter nuisance and invasive species from entering the aquatic ecosystem. It is imperative to use native plants rather than exotic species that are known to damage the habitat that nurtures beneficial fish, birds, and other wildlife.
Bioengineered erosion control technology is an excellent tool to restore shorelines and mitigate future erosion. Knitted ShoreSOX® and DredgeSOX® repurpose eroded muck by anchoring it to the shoreline for lasting stability. SOX solutions integrate naturally into the landscape and can be planted directly with vegetation for further erosion protection.
With riprap, rocks are placed over a filter blanket to keep the soil in place. Similar to riprap, root trap is achieved by covering the rocks with topsoil and installing native, deep-rooted plants that contain the sediment in place as they grow.
Bulkheads and retaining walls can be effective at controlling the effects of erosion; however, if not installed correctly, they run the risk of falling into the water or eroding from underneath and becoming unsafe.
Coir logs or fiber roll material can be installed to slow down the movement of the water or create a “pooling” effect that allows sediment to filter out. They can be made of natural or synthetic fibers or a blend of straw, coconut fiber, or polypropylene (plastic).
