Just got two 20 Gal tanks, both drilled in the upper left corner that I'm going to use as a sump.
The left side tank will house a refugium with an overflow to the right side tank (in through the bulkhead) for return pump etc. My question is: how much drop do I need for water to flow from the left tank to the right tank through the bulkheads & 1" PVC.
