so I just picked up a 225 set up, and need some help. I used to have a 125 but it wasn't drilled so I'm new to the whole sump action.
The tank is already drilled with two hole on either side but in the middle of the tank. The tank came with no plumbing so this is where most of my questions are. I want to put the boxes on the corners, I have two return pumps a 1200 and a 900, so what size overflow boxes do I use? Also have far down from the top do I put the top of the boxes?
