my last tank was a 110g was drilled in each corner for corneroverflows.in each overflow was two drains and one return.now it is physically impossible for water to overflow minus the bulkheads leaking( which is no different from the ring leaking that keeps the drain hose on a overflow box) each overflow has two drains in case one gets clogged.the only water that can enter the sump is the amount the sump had in it to begin with. i hated not knowing if what i had done was safe enough , turned out i was good but for how much longer??
