Hey guys picked up a 180g tank second-hand. Dual corner overflows with 2 1in drains in each, 4 holes total. Tank failed leak test nearly immediately, turns out there is a leak from the tank into the right corner overflow at the very bottom. My first action is going to be to dry the area and attempt a repair. If this fails I have a secondary idea, I was debating using the other good overflow to contain the full siphon and open channel lines of a bean animal. Use the bad overflow as a the e drain of the bean animal and a return. This way the water will not flood my sump, I realize flow in that bad overflow will be fairly stagnant. What about creating a black acrylic top and making it like a cryptic zone with a low powered powerhead to provide some flow to it? Plenty of powerheads for flow in the main tank. Not looking to move massive water through the sump anyway. Would this work if the repair doesn't hold?
