Wassup lyfr,
I too have a coy pond big enough for about 15 2ft fish, there actually pretty big and look tight like my butterfly coy's fins. The fins are so big it looks like wings flying under water. When i change there filter once a week i empty all the waste from it into a 5gal bucket and dillute it with water. I then split this 5 gal bucket into 20 gallons which i feed the outdoor crop with. I can tell you they love the fresh fish poo! It really greens up the leaf's and make them a healthy green. I have always wonderd if i could use styrofoam as a floating platform, cut a big 1 foot circle of styrofoam with a center hole puched out for the clone to be placed into and just let this float around the coy pond aimlessly. Any thoughts that this might work guy's??
