Thanks Jim. So let me make sure I understand this. 20 x 36 gallons = 720. Does this mean I should have 720 gph
flow from my power head(s)? If so, the two heads I purchased are each 750 gph
so I think I should either keep only one of those or the other option is to replace them both with the two 425s since it sounds like two heads creates better movement in the water. And the two lower flow heads are smaller. What is your suggestion?
