I'm new to the pond game - I had a family friend ask me if I could figure out why his pond didn't seem to have the 'life' it once did. fish are not reproducing plants are slowly dying off I bought a pond text kit and it tested high in phosphate levels. Homeowner fill the pond with tap water every night so I tested that also. Not nearly as high as in the pond, it was at typical levels for tap water. (pond came in at 2ppm). pH, nitrates, and ammonia all checked out OK. I am wondering what I can use, other than phos-out, (or in conjunction with phos-out) to lower the high levels of phosphate - I am thinking of plant material. Suggestions? Thanks guys.
