Understanding Water Hyacinths and Weed Control for Lakes

Aquatic plants can be very attractive and add to the appeal of your lakes and ponds. However, too much of a good thing can cause serious problems. That is why it is important to understand about water hyacinths and weed control. While they can be pretty, water hyacinths are not native Florida plants, and without proper weed control for lakes can quickly take over a pond.

These plants are aggressive invaders that can double in population in as little as two weeks. One plant in one season can multiply enough to cover one full acre. Each plant can grow up to three feet and have extensive root systems. While these root systems can provide protection for small fish and other aquatic life, and the seeds do appeal to some birds, when it comes to water hyacinth, a little goes a long way. Without constant monitoring, these plants can eventually cover the surface of a pond choking off the air supply and killing the fish that reside in the pond. A healthy marine environment requires the proper balance of fish, plants, and other aquatic life.

To maintain not only the beauty but also the health and balance of the water features on your property, choose a team of skilled professionals that have extensive experience in weed control for lakes. Such a company can ensure that your lakes and ponds maintain the proper balance to enjoy good health and lasting beauty.

Know When Your Pond Aerators and Fountains Need Maintenance

The best equipment, including pond aerators and fountains, is useless when it is not properly maintained. Your water features are one of the things that attract guests to your hotel or resort, tenants to your apartments, and homeowners to your condominium community. Keep your ponds and lakes looking their best with routine maintenance for pond aerators and fountains.

When the bodies of water at your university, shopping center, business park, or government complex show signs of imbalance, such as weeds or algae, that is a sign that a problem exists. If your pond aerators and fountains are not working as they should and oxygen balance is not maintained, the entire aquatic environment could collapse. Without proper aeration, the fish will not thrive. When the fish population diminishes, the plants on which they feed can soon grow out of control. This overgrowth can cause additional problems. That is why, at the first sign of a problem, you should call upon the experts to have your equipment repaired or replaced if necessary. Once the proper oxygen balance is restored, the rest of the pond or lake can return to a state of health and beauty.

The company that you choose to partner with for repairs to this important equipment should be experts in their field. In addition to fixing common problems, they should be well versed in installation of pond aerators and fountains as well as all other facets of lake management. In that way, you can rest assured that there isn’t an issue with which they are not familiar and can’t repair.

Keep Oxygen Levels Up in Your Lake with the Right Aeration System

The primary purpose of aeration in pond and lake management is to increase the oxygen levels in the water. There are different methods for doing this, including injecting air, mechanically mixing or agitating the water, or even injecting pure oxygen.

Destratification is a type of circulation that thoroughly mixes the water layers of different temperatures in the lake.

Here are the most common systems for lake aeration.

Air Injection (Diffuser Systems) – The most common method, air injection systems, consist of a compressor on shore delivering air through lines to the bottom of the lake.  The rising air bubbles cause colder water to rise and mix with the warmer water.

Mechanical Flow Pumps – A floatation platform and frame support an electric motor and a large propeller. The propeller pushes the water from the surface downward, setting up a circulation pattern.

Surface Spray Units – This lake aeration system consists of a float with an electric motor-driven impeller. The turning impeller pulls water up a long vertical tube and sprays it above the water’s surface in a fountain effect.

Impeller-Aspirator Systems – These consist of a float that supports an electric motor-driven impeller at the bottom of a hollow shaft that extends down toward the deeper water at an angle. The impeller propels the water into the air.

Pump-and-Cascade Systems – This lake aeration system is a large pump that moves lake water to the top of a ramp chute. The water cascades down the ramp and falls back into the lake.

The Four Main Types of Pond Weeds

It can be challenging to keep your pond weeds under control. You will first need to identify which specific weed is your main nuisance plant, as you wouldn’t want to start the wrong type of treatment. Additionally, some pond plants are beneficial to local and migratory wildlife.

When it comes to aquatic weed control, pond weeds can be easy to identify.


Algae are a common nuisance with no defined root system. Some, like planktonic algae, are microscopic, while others resemble land plants, except that they lack roots. It often floats on a pond’s surface in sheets but starts life at the pond’s bottom before floating to the surface.

Emergent Plants

Emergent plants are rooted plants often found along the shoreline. They stand above the surface of the water, like cattails. The stems or stalks of emergent plants are somewhat stiff or firm. You will want aquatic weed control for some common emergent weeds are alligator weed, water pennywort, and smartweed.

Floating Plants

True floating plants are not attached to the bottom of the pond. Some varieties can grow to over a foot in diameter, like the water hyacinth. Most have roots that hang in the water from the floating green portions. Duckweeds are a good example and form dense blankets that cover the surface of the water.

Submerged Plants

Of the underwater pond plants that require aquatic weed control, Hydrilla is one of the worst submerged weeds. It grows quickly and has long leaves and sharply serrated edges. Its leaves are quite rough to the touch. Flowers grown from their upper branches are translucent to white.

Why Use Aerators and Fountains for Ponds and Lakes

Adding air to a pond has a hugely positive impact on the ecosystem. It circulates water, disrupts mosquito breeding, adds oxygen for fish and other critters, and it helps prevent algae and other weeds. Aeration is by far the best value for money in terms of good pond health.

Aeration can come in many forms: aerators, fountains, windmills, circulators, and electric compressors. By far, the most common are pond aerators and fountains.

Pond aerators and fountains provide lovely visuals; this is true for fountains, especially, and aerators to a far lesser degree. Both mechanisms hang under a donut-shaped float and use a motor-driven propeller to shoot water up into the air. The main difference between a fountain and an aerator is that a fountain forces the water through a nozzle at high pressure, creating a specific display, whereas the aerator has no nozzle.

Using pond aerators and fountains do not provide the same oxygenation at the bottom of the pond as an air compressor, and usually isn’t as successful at fighting algae and weed growth. Pond aerators and fountains will circulate the top layers of water, keeping the pond surface free of scum and tree pollen. The benefit of this function is that they do not disturb the lower levels of pond or lake water, ensuring a better environment for trout and other cold-loving fish. Another advantage with pond aerators and fountains is that they do an excellent job of aerating shallow water bodies where you may otherwise need a large number of diffusers or an air compressor.

Keep the Pond in Your HOA Community Free of Weeds

When they overgrow, pond weeds can become unsightly and stunt fish growth.  Pond weeds usually start by someone adding plants to the pond, but they are then not managed and get out of control.

Here are a few possible methods to address weed control for lakes and ponds.

Many chemical options have warning labels, which state that for your safety and the environment’s safety, only 1/3 or 1/2 of the pond can be treated at a time due to the mass of dead, decaying weeds. More than that and it will risk a large scale fish kill.

There are tools to help make weed control for lakes and ponds easier, like extended weed cutters and rakes.

An eco-friendly approach is to use triploid grass carp, which eat weeds. However, there is a permitting process, and you need to do some research, as some species of weeds are not on their dietary list.

A Lake Bottom Blanket is another non-toxic option.  It covers and suffocates the weeds but does not suffocate the floor of the pond harming the smaller life.

Once overgrown pond weeds are addressed, then a proactive approach to weed control for lakes and ponds will ensure that they do not return. Installing a properly sized aeration system will provide oxygen in the water and help beneficial bacteria. You can add some “Muck and Sludge Remover” as well, to reduce the mucky bottom and even add some pond dye to the water to turn it a pleasant color.
