Drilling tanks: Pros/Cons

[reefburnaby]

Hi,

I would recommend drilling too. From experience, flooding will happen eventually with overflows - stupid snails!!! I drilled a 1.5 inch bulkhead in my 90g with water in it. I drilled through the back panel - 8 inches from the top and side and its 1/2 inch thick. I had it running for 2 years and it seems to be doing fine.

37G? Probably two 1 inch bulkheads will be fine. How much flow are you gonig to put through those bulkheads?
