if you are planning on any corals at all, I would definately aim for minimum 30x tank size.
Well if anything ive learned that the specs on the websites are misleading. It says the AQUACLEAR POWERHEAD 50 has 270 gph and is good for tanks up to 50 gallons. Haha turns out ill need at least 3 of them to get enough gph!
