So my 20 gallon nano reef is up and running. I have got everything running how I want except water flow. I have a seachem tidal 55 filter on it with the skimmer producing 250 gph of glow . It’s not stagnant , but I need more flow. I purchased the smallest power head I could find and it is a 660 gph. Much too much. Right ? The fish can’t swim , the sand doesn’t blow that much tho . Anyway I ordered an eflex wave maker accessory for my USA loop , that is adjustable down to 132 or 135 or something like that. In the meantime , my question is , More flow with the big power head or leave it until the new one arrives ? Thanks guys
