Per gallon, How much water flow


Should you have for a reef tank? I need some suggestions it seems I have too much garbage sitting around in my 72gallonBF. Any way to figure this out?

The minimum that most will say is about 10 - 20 times the water volume, so for a 72g, you are looking at 720gph - 1440gph. However, corals can't move like fish to get nutrients, they require them to come to them via water flow. I have 25 times flow in my current tank and I can tell you it is not enough to keep things clean. I am putting together a 75g and that tank will have about 65 times the water flow or about 4500gph flow. Of course, the type of corals you keep also play into the flow needed. Soft corals don't typically like a lot of flow and SPS do.

Sometimes it seems like a voodoo science. There are a lot of factors that can play into it, particularly the species housed in the tank, but also things like aquascaping, substrate, feeding habits, husbandry routine, etc. General rules of thumb are a bit dangerous, but as a benchmark softies would be more in the 10-20 range and stony corals more in the 20-50 range. That's not to say that a stony tank couldnt thrive in a low flow setup (or softies in a higher flow setup), again it depends on the specifics.

If you'd like more direct advice, could you post some pictures of the current setup and describe the inhabitants that you do (or would like to) keep?
