how many gph should a 46 g tank have? keeping corals and an anemone
rigdon87 Member Mar 6, 2009 #2 the minimum for a reef tank is 25x per gallons so your tank would need at least 920gph but it all depends on what you want in your tank, some corals and anenomes require strong flow and some need medium to lowflow
