After a terrible spring for murky water, plants have finally taken over the filtration of ponds.
Another two weeks of this weather (80's) and every pond with 50% or more plant coverage will naturally clear up.
The two main causes of algae are:
A.) Too many fish.
B.) Not enough plants.
We have algaecide, ion-gens, & uv clarifiers available if you aren't able to stay on top of the algae with plants alone.
