SOLitude Lake Mangement - 7 Natural REmedies for Sustainable Lake Pond Algae Control
There are a variety of algaecides available that work well to reduce algae problems in your lake or pond. In many cases, it is recommended to use an algaecide to eliminate unsightly algae blooms as they pop up. However, simply treating the algae alone is only a short-term solution to what is often a larger issue.
Successful long-term algae controlinvolves implementing an annual preventative management plan in order to create and maintain a balanced aquatic environment. And you’ll be pleased to know that there are a number of environmentally friendly and effective water quality restoration methods that can be utilized to help prevent the conditions that might otherwise lead to excessive or toxic algae blooms. These natural and ecologically balanced methods will help improve water quality and reduce the potential for algae blooms, resulting in a healthier and more beautiful ecosystem.
Here is a look at seven of the ecologically balanced options for sustaining your water quality:
1. Limit Runoff Caused by Human Activity
One of the main goals of successful algae control involves limiting excess nutrients in your waterbody. Nutrient loading is usually caused by stormwater runoff and organic debris that enters the water. Reduce the amount of problematic nutrients in your water by limiting the use of fertilizers, bagging your grass clipping, and keeping leaves from getting into your lake or pond.
2. Plant Beneficial Vegetation
Having the right types of plants around your lake or pond can also help keep unwanted nutrients out of the water. A beneficial vegetative buffer may include aquatic plants such as pickerelweed, blue-flag iris, swamp milkweed and cardinal flower. Grass-like native sedges and rushes are also a great choice, as their shallow spreading surface roots hold shoreline soil well.
3. Add Dissolved Oxygen with Aeration
Lake and pond aeration systems increase diffused oxygen in the water, which reduces the effects of nutrient loading by accelerating the breakdown of organic matter. Either a submersed air diffused system or floating fountain can be used. To further reduce your environmental footprint, consider asolar powered aeration system. Solar lake and pond aeration systems are similar to traditional systems, but have a compressor that is connected to a solar panel as opposed to an electrical power source. In addition to those with a concern for environmental sustainability, solar powered aerators are also a good choice for properties where it is difficult to obtain electrical service.
4. Consider Biological Augmentation
Biological augmentation involves introducing formulations of beneficial bacteriaand enzymes into your lake or pond. These bacteria accelerate the decomposition process of organic matter and consume nutrients, which can be beneficial in helping to reduce algae. Bacteria products are often utilized as part of an annual lake or pond management plan, and better results are often seen when formulations are used in conjunction with aeration.
5. Bind Available Phosphorus
Phosphorus is the nutrient used by most algae, and there are products available to reduce the nutrient load in your lake or pond. Phoslock, lanthanum modified clay, can be used to bind phosphorus in the water column and is also effective in locking up the phosphorus in the bottom sediments. For chronic nutrient loading, Alum (aluminum sulfate) can also be an effective management strategy for helping to restore water quality.
6. Use Lake and Pond Dyes
Nearly all aquatic plants and algae require sunlight to grow. For this reason, lake and pond dyes are often used as part of a successful management strategy. Regular application of blue or black dye can help limit UV penetration in the water column, restricting the necessary light that algae need to thrive. Most aquatic dyes are non-toxic and environmentally friendly, and will not harm fish, birds or other wildlife.
7. Utilize a SonicSolutions Device
Specific algal species are vulnerable to ultrasonic sound waves. SonicSolutionsis a proven technology used to combat algae without the use of chemicals. Using ultrasonic sound waves, the device pops gas bubbles in algae cells and breaks bonds along the cell walls by honing in on the resonance frequency of algae cells.
As algae die and decompose, they release nutrients back into the waterbody which eventually leads to additional algae blooms. Therefore, it’s necessary to take a proactive approach to algae control, and a comprehensive aquatic management program is the best way to maintain a healthy lake or pond.
