I have just purchased a used 125 gallon that came with a refugium and pre-drilled holes in the back glass. you can screw the plumbing onto the backside of the tank...but it has eight holes, and i don't know where everything should go or should i plug up a couple holes. All I need to know is what kind of plumbing to get. they're also 1 1/2 inch, and how big of a sump pump do i need or should i use 2. This is because the sump has 2 outlets.
