Algae in ponds occurs naturally. A healthy pond always has some algae and algae production is required for a healthy fishery. Excess algae is an indicator of too many nutrients in the pond and usually leads to noxious odors, muck build-up and the problem gets worse as time goes on.
First, lets address your algae bloom. Use our Lake Rake to clear the algae from the pond. Removing surface algae is a great natural alternative and begins to stop the cycle of decomposing algae adding to the nutrient load.
