not sure where to post this so i tried a few different places

ok so after reading a little and looking at some things online, it sounds like i will need between 1-1.5" bulkheads, what do you guys think? i am looking at BRS to buy this at when we get our discount next month and i am thinking about buying a new tank for the sump so i can start to build this now and possibly have the entire new system up in one day so i do not have to worry about pugging holes and unplugging. just seems easier to have the new system start on the same day....what size hole do you think will be best for the overflow?

this is going to be for a 40b with a 20 sump.

1" bulkheads will gravity flow 600gph. Unless you plan to have a hurricane style biotope, I dont think you will need anything larger than 1".
