Aquarium, Pond, Lake and Fountains - Algae, Water Dyes and Water Treatments


Tried other treatments for green water with minimal results, water was so green before I added hydra crystal and could hardly see my fish, 5 days after treatment and cleaning the filter twice I can see the bottom of the pond.
