Brenda S asked: I have a pond with goldfish, Koi, and a couple of plants. I have two small waterfalls and a spray to help keep the water ventelated for the fish. With the hot weather here in MN this last month - the water is really green and the rocks have algae. I do feed the fish food - if I stop feeding the fish will that actually help the water clear up or is there something that I can put in the water to help?
