Well I have 75 gallon tank, two maxjet 1200 series. The only problem I have is how much water flow do I need. One person suggest that take your total gallon of your fish tank multiple it by 20, which going to give you the tatol flow you need in your tank. But it seem to me that I don't have enough water flow because I'm see a lot of debris underneath my LR especially in dead spot. Any suggestion on how I can resolved these
Thanx
