I wanted to build a sump for a 70 gallon reef tank with an internal overflow (tank not built yet), out of a 29 or 30 gallon tank. My problem is, I don't know how high to make the baffles or how much water to put in the sump. Anybody with any advice or helpful websites, I'd be very grateful. Thanks.
