Okay so I have a large sump, looks like its probably for about a 200 gallon.(pic)
And it looks like I'm ethier going to have to get two over flow boxes or one larger one.
I like the CPR over flow boxes, but it would be cheaper to get the larger one than two smaller ones.
The smallest large one that's has two bulkheads has a flow rate of 1200 gph
, is that way over kill for a 100 gallon tank?
I would need a 1200 gph
pump aswell for my return?
