I think if like to get in on this, if anyone can answer, help me out. I have a 60 gallon (4') tank and I only use 1 Koralia 1150 gph powerhead, I don't need a lot of flow for my tank. Would it be best to go with the wp10 since they seem to crank pretty good? The wp25 will be too much flow for my tank. It's all softies and some euphyllia. Thanks for any help!
