So. I've posted in a different thread that I am going with Glass Cages for my tank. It comes with one return and one drain hole with two bulkhead holes. I want two returns going to tank from the sump so I'll be getting an extra return drilled out.
Query #1: What would the bulkhead holes be used for? And.....
Query #2: Should I have 2 drain holes as well?
I'm doing this right the first time so I am looking for any and all experiential advise I can get on the matter. The tank is going to be between 90 and 120G (not decided on actual size yet). TIA.
