Hey guys new to the forum, I have a 100 gallon FOWLR and a rsm130d coral tank all doing great. Just bought a 225g dual overflow tank to replace the 100g. Each overflow have two 1-3/4 holes so that’ll fit 1” bulkheads. I’m going to use a trigger ruby 36 sump. I’m trying to figure out how to plumb this. Do I do a drain and emergency drain in each overflow.
