Hi, I'm new to ponding and this thread directly addresses my issue. I have a drop in liner, the bigger one. I think its about 300 gal from my calculations. I have a skippy filter going and about 40-50 goldfish less than three inches, mostly less than two. I have two problems which are playing on each other. I have foamy green slime in my skippy that plugs up my drain which is a two inch sink drain and my pump keeps getting plugged up with fish, um, poo. Also my pump hose is plugged up. advicIt has been set up foie a few months adhd has four large water lilies. Any advice? I dont want to clean my skippy and kill my good bacteria, I know better than that at least. I do have algae but not really bad. Mostly on the ramp that makes my little river leading from the output and in the filter. If it helps I'm in fort worth, tx and its a thousand degrees here right now.
