Hello June of ast year my husband and I were fortunate enough to buy a home with a beautiful water feature. It is basically a large circular shape cut into the steep slope of a hill and has two water falls cascadindind down each side emptying into a pond. When I adopted the pond I knew NOTHING about keeping a pond but I have been working hard to get up to speed on how to care for it. Last year I reconditioned the water and after rigorous testing decided to try three fish. Well, the fish did well and even though the pond froze during the winter except for the water falls flowing into a narrow slit the fish survived into spring. After my initial success I added 9 more fish. So Now my fish family includes 5 Sarasha Comets, three Shubunkin, one comet, three koi, 10 giant pond snails, one bull frog tadpole and several Pickerile frogs that adopted us. The pond gets full sun in the afternoon and for this rason I tried to get a lot of plants for shade. I have five varieties of Lillies, a papyrus, dwarf palm, some violet stemmed taro, aztec arrow, hyacynths, pond lettuce and a couple of left over volunteer parrot feather from last year. My BIG problem is STRING ALGAE!!!!! HELP me!! Please. It is a constant battle. I reead something on the forum last night about how much I am feeding my fish and that because of this they are not eating any algae and that their waste is upsetting the balance of the pond and counteracting my efforts to beat back the algae. My question is this: since I have been spoiling my fish by feeding them peas, koi pellets, flakes and krill will it hurt them to drastically cut back on this amount of food?
