Hi everyone was wondering what is recommended 2 overflow or 1 going with a 180 gallon tank. Not shore in this area, like some advice suggestions before I buy tank what size drains. Thanks
 
It depends on the size of the PVC also are you drilling the tank or the overflow U shaped option. 1 inch PVC drilled through the back I think maybe even 3 overflows.
 
Ely thanks 2 drains, so water will drain into drains then return from pump. How many return pump needed for a 180, I'm lost a little here. I hear it will be noisy, how will I setup drains. I want a good setup easy to mantaince, protein skimmer goes were drain is. Thanks
 
What size is the overflow? After you know that then you will need to know the GPA rate for each. Then the return should be double the GPA from your intakes.
