I have a 120 reef ready tank that I recently tore down due to me moving in a few weeks. I think I am going to replace all of the bulkheads because a couple of them had salt creep around the gaskets. It has dual corner overflows. Does anyone know what size bulkheads it came with? I'd go measure but it's in storage. I think it was 1" drains and 3/4 returns?
