Bulkhead

misguided

I dont know wether to go with a 1/2" or 3/4" bulkhead im just hooking a canister filter up to it since i cant fit a sump under my hexagon except a hexagon so? The tank is going to be FOWLR
 
The cannister should be fine with just 1/2".

However, I believe when in doubt, go bigger. You may change your setup later and want more flow.
