Ok. I have a 3500 gallon koi pond set up in a very formal style. only problem I have is keeping it clean. Right now the only filtration on it is a large skimmer and bio-balls in the waterfall. I have a 100 pound sand filter I think I could put in line on it, but would a pool sand filter work for pond like this? btw The pump is a 3000gph pump.

right now its at 60 degrees still warming from winter and is clear. no nitrates detectable by drop test. it gets a lot of algae in the filter though
