			 For a 90 gallon you'll probably want at least a 20 gallon sump in order to fit the required equipment. The more space you have to move around in the stand/sump area the better, otherwise it gets frustrating and overcrowded really quick. Remember that the sump is only about half-full, so you aren't actually adding 20 gallons to the system size.

			 Haha, gotta love physics. It's a big puzzle of baffle heights, pump sizes and water flow.
