Hi all,
I am looking at a 5ft 120 gal tank locally but it is undrilled. The guy selling is going to get it drilled and add an overflow but I am not sure how many holes to drill. I am limited to the 700gph my overflow can handle now and need to have more flow. I was thinking of doing 4 holes 2 drain and 2 for returns. If needed I could use the returns for a closed loop?
If this was your tank, what would you do
