I have a 160 gallon tank, it already has 4 holes drilled in the back. I am planning to drill 2 additional holes for a total of 6. My plan is to install 2 internal overflow boxes with 2 bulkheads each and use the remaining 2 holes for returns.
So my question: almost all posts I see are on reef ready tanks with the holes drilled through the bottom of the tank. Is there a variation of the "Herbie Style" drain that can be adapted for a thought the back of the tank installation? Or is there a better style drain?
