murky pond water
I have had my pond for 1 month now and it started out clear. It has gradually became worse to the point of not being able to see the fish. It is a 500 gallon pond with 4 goldfish and 3 snails. It has morning sun up until 1:00 and then shaded by a tree. Last week I placed 6 big bunches of hornwort, 3 bunches of hyacinth, and a lettuce plant. We have been treating it once a week with "Jungle" Clear-Zyme Concentrate. What do I do now??
