My new pond (3 months old) is so pea green. I have ordered some Tetra pond water clarifier. Has anyone ever used this product before and does it help? My pond is about 8 x 16 (about 500 gallons). I have added 20 baby goldfish (the water is so bad that they cannot be seen - so I assume they are still in there). I have some water lilies and some water lettuce and water hyacinths (small). I had been using quilt batting but quit using it because it did not seem to help. I have been adding bacteria from Aquascapes using it per the directions. I need help!!! I am so discouraged. The water clarifier that I ordered will probably arrive tomorrow. Will I be making a mistake to try it. At this point I am ready to drain the pond and call it quits. Everyone who visits to see my "NEW POND", says oh my goodness, what's wrong? Any help will be appreciated.
