I have a single-bulkhead overflow box, with the standard j-tube. No brand on the overflow, its just black acrylic on the inside, clear on the outside box. The outside box is deeper than most - a good 10" deep.
I've added a second j-tube to increase overflow rate, but I know I'm limited by the single 1" bulkhead.
If I replace the bottom plate of the outside box, with a DIY piece with 2x1" bulkheads, would I be getting the typical 1200GPH that most of the new ones claim to offer?
I'm working on increasing flow in my minireef to 10 times turnover, and the overflow is the first step... (wouldn't want to add a 1100GPH pump with a 350GPH overflow
