Yes, floating covers are effective in reducing chemical use in water treatment. Oftentimes, algae growth in uncovered ponds can require expensive algaecides and other chemical treatments in order to control algae populations. Using a floating cover reduces algae growth before it starts by blocking sunlight, an essential piece in algae photosynthesis and growth.
Floating covers also decrease the need for other extensive chemical disinfection and filtration processes by protecting the water from debris and contaminants. Reducing this contamination and algae growth results in a decreased reliance on expensive chemicals to maintain water clarity. This results in not only cost savings but also a more environmentally friendly approach to water management.
