Understanding Pond Bacteria and Enzymes

Bacteria have a bad reputation, but they play an important role in maintaining the health and beauty of a pond. Likewise, enzymes are essential for keeping ponds in balance. Read on to learn more about these natural organisms’ roles in helping your body of water look its best—and how your property can benefit from bacteria or enzyme therapy treatment.


Pond Bacteria


Bacteria are the foundation for your pond’s animal food chain. They decompose waste products and assimilate their nutrients. In turn, they are consumed by small aquatic organisms that become the food for fish, insects, and other creatures.

Depending on the type of beneficial bacteria treatment you use, bacteria can reduce “muck” on your pond’s floor, improve its water clarity, and slow algae growth. Talk to a pond maintenance expert to determine what kind of bacteria would be most helpful for your property and your goals.


Pond Enzymes


Enzymes are amino acid chains that catalyze chemical reactions by breaking some molecules apart and putting other molecules together. They perform the vital function of controlling the build-up and decomposition of essential matter in vegetable and animal organisms.

The right enzyme treatment will boost your pond’s digestion of everything from leaf litter to goose manure. Enzyme therapy can also augment your bacteria treatments. Explore the many different pond maintenance products available and find the ideal solution for your property by consulting with professionals.

Florida Pond Maintenance Tips: Natural Weed Control

Summer is a prosperous season for aquatic weeds, which can cause headaches for anyone trying to keep their lake or pond a beautiful, blue hue. Here at The Lake Doctors, Inc., we recommend following these weed control tips for easier pond maintenance in Florida.


Plant Trees Around Your Water Body

Weeds need warm temperatures, sunlight, and nutrients to prosper. Planting trees around the perimeter of your pond or lake is a good way to reduce the availability of all three. The shade from the trees will keep the water temperature cooler and block some sunlight. Furthermore, their roots will take up some of the nitrogen and phosphorous that would otherwise nourish the weeds. Talk to our team to learn more about using trees as a natural form of aquatic weed control.


Introduce Herbivorous Fish

Most people are familiar with how a herd of hungry goats will keep a field well-trimmed, but many don’t realize that fish can do the same for a body of water. By introducing sterile carp, tilapia, or other herbivorous fish to your property, you’re adding another type of weed control for lakes and ponds. The fish will eat the vegetation and help keep it in check. Consult with our experts to make sure you stock your water body appropriately.

The Benefits of Fountains and Aeration Systems

Water features add a lot to your property, and beyond their sheer attractiveness, there are many other benefits to having fountains and aeration systems. The Lake Doctors, Inc. specializes in pond maintenance in Florida and will use this blog post to discuss those benefits.


The very first thing we want to point out is that ponds, fountains, streams, and waterfalls do much more than elevate the aesthetic impression your property delivers. It is well known that water has a relaxing impact on people. If you think about the peace, you feel when sitting lakeside or at the beach, you will see the veracity in this statement; when you add extra features such as lights and variable spray patterns to your fountain, the appeal increases.


Pond fountain installation and aeration systems elevate the quality and your enjoyment of your water features in many ways, including:

  • Maintaining lake and pond health
  • Creating a healthy environment for aquatic life
  • Improving and stabilizing water clarity
  • Reducing or eliminating unpleasant water odors
  • Minimizing organic sediment accumulation
  • Combating algae blooms

7 Tips to Keep Pond Water Clean

When it comes to maintaining a pond habitat, it is important to keep in mind just how crucial good quality water is when it comes to keeping your fish and flora happy and healthy. While some might think that clear water means good water, that simply is not the case. Thankfully, there are some lake and pond management tips that you should know to keep your pond perfect for flora and fauna alike.

Maintain a Healthy Fish Population – Too many fish in your pond can cause over-population. An excessive number of fish means an excessive amount of fish waste, which can cause an imbalance in your pond water. If you notice more than 10” of fish for every 100 gallons of water, it is time to consider rehoming the excess.

Don’t Over-Feed Your Fish – If you put more food in your pond than your fish can eat it can end up rotting and decaying. Choose a quality fish food—one that floats—and then feed your fish once per day. You should never feed them more than they can eat in 2 to 3 minutes.

Create a Proper Balance of Plants – At the season’s peak, you should have between 40% and 60% of the surface area of your pond covered or shaded by plants.

Choose the Right Size Pump for Your Pond – You should be circulating the entire water volume a minimum of once every hour for a healthy pond.

Clean Debris from Your Pond Before It Can Decay – A pond skimmer is likely to remove most of the debris from the surface of your pond, but it won’t be able to get everything. That is why it is essential for you to remove any fish waste, leftover fish food, sticks, and leaves that the skimmer misses avoiding an increase in ammonia levels.

Choose Proper Filtration for Your Pond – Just as important as your pond pump, your pond filter should match the size of your space. It is always a good idea to up-size your filter to handle more than the capacity of your pond. Also, remember to clean your filter regularly, following the manufacturer’s instructions.

Keep Your Pond Cool During Hot Summer Days – When the temperature starts to climb outside, it can warm up your pond. When the water in your pond exceeds 75 degrees, it begins to have a difficult time retaining acceptable levels of dissolved oxygen—which is critical for fish health. With the proper pond shading, you can help keep your pond water cool so your fish can breathe as usual, even during extreme heat.

Taking care of a pond or water garden is a lot of work if you are trying to do it on your own. However, there are options that will handle all of the work for you, including our location in Tallahassee, FL. With the proper pond management and pond maintenance, you can enjoy a beautiful exterior design element that will keep your space looking it’s very best.

UPL NA Inc’s Aquatic Drone Boat Development and Commercialization

In this article, we’d like to introduce you to a new and useful tool the UPL NA Inc (UPL) Aquatics Team has been working on for managing aquatic plants and algae. It’s an autonomous aquatic drone boat! For the last few years, we’ve presented general updates and most recently brought an actual field-tested model to aquatic plant management conferences. We’re excited to share some details about the boat’s development to date, specific features of the boat, and welcome your interest in future testing and possible purchase. Almost everyone—especially those in the aquatics industry—is trying to do more with less, and there is a significant need to be more efficient. Technology is changing at a rapid pace to help save time and make tasks easier thereby increasing our efficiency and improving life in general. With that in mind, UPL has collaborated [1]rated with North Carolina State University (NCSU) since 2016 on the development of an autonomous drone spray boat named ADAPT™ (Aquatic Delivery Autonomous Precision Technology). The driving force behind the project was to offer a versatile, easy-to-use, pesticide delivery method that significantly reduced the exposure potential to the aquatic applicator. When the partnership between UPL and NCSU (Crop Science and Mechanical and Aerospace Engineering departments) began on developing the ADAPT™ spray boat, a provisional patent along with initial boat design was filed and project implementation began (Fig 1). The rather rudimentary boat had no chemical tank and was propelled by a small fan. Initial tests were promising; however, there was a problem with the boat tracking off-course in moderate winds. By the third generation (Fig 2), the previous tracking issues were resolved by replacing the fan propulsion with a lower power (~50# thrust) trolling motor, and the boat was lengthened by several feet to make room for a 10-gallon spray tank. Several trials were conducted with this iteration—including a full-scale treatment of roughly a quarter-acre pond for watermeal/duckweed—and resulted in excellent control (Fig 3). The next step in the evolution came with a manufacturing agreement with RMD Systems (San Luis Obispo, CA) in 2019 which significantly added more capabilities and capacity to the boats. By using many off-the-shelf parts, we are able to keep the cost down, while also offering a great deal of versatility. This allows the boat set up to be designed for an applicator’s specific needs. The current generation ADAPT™ spray boat has the following specifications and capacities (Table 1) in addition to the autonomous mode feature. A predefined track can easily be created and stored in the boat’s onboard memory, allowing the boat to automatically run the track in autonomous mode when directed by the applicator. An enhanced feature of autono[1]mous mode is the ability of the applicator to set specific waypoints to turn on and off the spray pump.

ADAPT™ is equipped with several safety features including a first-person, real-time video camera mounted on the bow which transmits a video feed to the applicator on the smart controller (Fig 4). Redundant GPS receivers, inertia meters, and compasses significantly reduce the pos[1]sibility of a “fail-to-run” situation. The boats have software that returns the vessels to the original launch point (also known as the “return to home” feature) when the batter[1]ies are running low or a loss of signal from the controller is detected. Lastly, ADAPT™ is equipped with LiDAR (light detection and ranging) sensors on the bow to stop the boat while running in autonomous mode when an obstacle is detected. Recently, UPL placed 3 boats in the hands of professional applicators for real[1]world testing to receive feedback on the current utility of the platform and evaluate potential changes to make it more useful. Particularly noteworthy was a trial conducted by The Lake Doctors, Inc (hereafter TLD). In May of 2021, TLD staff from the Jacksonville office and regional manager Sean Fleming simultaneously conducted an algae application and mapped a two-acre pond for bathymetry and sub[1]mersed aquatic vegetation using an ADAPT™ boat w hi le in autonomous mode. The mapping effort was repeated twice while on-site to document the accuracy of the guidance system. As you can see by the tracks in Fig 5, the boat maintained a very accurate path as evidenced by the overlayed image of the two tracks. Another evaluation was also performed to compare the ADAPT™ mapping accuracy to a typical application surveying vessel (i.e., johnboat operator-driven) used by TLD. The results were very comparable, ~75% similarity between methods to collect the data. It was noted that the accuracy rate would be higher if the transducer on the ADAPT™ was calibrated (position of the transducer relative to the water’s surface). Both trials were performed relatively quickly for the size of the pond evaluated. The ADAPT™ platform is tailored for multitasking as demonstrated in this trial that was completed in 25 minutes. Sean stated several key findings in the conclusion of his report. “Running in autonomous mode may allow for placement in difficult to access locations for treatment or bathymetric analysis. The autonomous mode would allow for precision treatments at specific areas of a waterway with confidence that the pathways would be followed. This would be most beneficial in developing tracks based upon biovolume maps generated. In such applications, the initial scan would flag the areas of greatest biovolume accumulation (Fig 6) and the subsequent runs would be able to precisely target those areas based upon GPS data rather than a visual line of sight. This would be particularly effective for areas of underwater vegetation deep in the water column. The trailing hoses can be set to the precise depth based upon the contour measurements to more precisely deliver herbicide to the target species.”

An Annual Pond Management Program is Worth the Investment

That overgrown pond on your property would be great for fishing with some needed improvements. Among these would be reducing algae and weeds, introducing beneficial plants and fish, and stocking game fish. With an annual pond management program, you create a healthy pond filled with healthy fish.

It might seem as if it were more valuable to leave that body of water as it is in nature, but with the assistance of highly qualified technicians, it can be clean, healthy, and productive. These professionals have the education and training to turn that pond into your favorite fishing hole.

Testing, Treating, & Stocking

The transformation begins with an annual pond management program. This way, the technicians can determine what your pond needs:

  • Reduction of Weeds & Algae
  • Water Testing for Clarity & Chemistry
  • Inventory of Plants & Fish
  • Weed & Fish Management
  • Water Treatment
  • Fish Stocking
  • A Sustainable Environmental Management Plan
  • Regular Reports & Corrective Action

Over time, you’ll see the improvements in your pond as the weeds and algae give way to healthy and beneficial plants. The water becomes cleaner and clearer, and the fish start reproducing. Other benefits include improved drainage and increased real estate and recreational value.

Dealing with Snakes around Your Pond – A Natural Approach to Pond Management

water snakeYour pond may be part of a thriving ecosystem. As a water source, your pond is attractive to many wildlife species. Each species plays an important role in maintaining the balance of the local environment. Of course, this means you are likely to encounter some perhaps less-than-welcome animals as well. When you find snakes around your pond, you may be alarmed. But there are pond management strategies you can implement to help you control their presence.

The first thing to remember about snakes is that you are much more likely to come across a non-venomous than venomous species. Common species in North America, such as northern water snakes, black rat snakes, garter snakes, and corn snakes, may seem creepy to some people. But they are harmless to humans, and they feed on other animals such as mice.

If you aren’t very familiar with snakes, it’s best to err on the side of caution – do not approach or provoke the snake. On the other hand, if you have identified a venomous snake, contact a professional wildlife control company.

As far as managing snakes around your pond, there are several varieties of plants you can use. Some species of plant repel snakes because of their scent or deter them because of their appearance. By surrounding sections of land with these plants, you can help ensure that snakes stay away from that immediate area. Pink agapanthus, lemongrass, marigolds, sarpagandha, wormwood, and mother-in-law’s tongue are said to be effective in keeping away snakes.

Lake Aeration Systems 101 – What You Should Know

lake with a fountainProper oxygen levels are just as vital to the health of a water body as they are to a human body. In ponds and lakes, fountains and aeration systems are essential for controlling algae blooms and preventing fish loss. And since cold water holds more oxygen than warm water, aeration systems become especially necessary in the summer months.

The most common forms of aeration are surface aerating fountains and submersed diffused air systems. Both systems work by introducing and circulating oxygen throughout the pond or lake. However, submersed air diffusers use a compressor to pump air through tubes, which releases the air in bubbles from the bottom of the pond. Fountains, on the other hand, spray surface water upward, which aerates the pond as it splashes down again.

Depending on the characteristics of your body of water, one of these systems will likely be more effective than the other. For example, a shallower pond will benefit more from a fountain since aeration occurs on the surface. Deeper ponds will require a submersed diffuser to ensure that the water is consistently oxygenated.

Consulting with a professional water management team is the best way to ensure that you have the right aeration system. At The Lake Doctors, Inc., we are available to assess your pond or lake and recommend the best solution for you.
