Pond Algae 101 - Why your pond is green

Ponds often become challenged by pond algae, pond scum and other aquatic plant growth. This can be unsightly, produce a pond odor, cause fish kills and provide fertile breading grounds for mosquitoes.

The root causes of this pond algae are the excess nutrients, such as fertilizers, leaves and waterfowl excrement that enter the pond via storm water runoff. These nutrients fuel aquatic plant overgrowth and suck the oxygen out of the pond - killing the ponds ecosystem.
