help with plumbing sizes

[richy's reef]

hi, im just about to order my glass to build my own aquarium, im just after some feedback on what size bulkheads are best to use. tank is approx 500L plus sump. is 32mm drain and return going to be big enough? i have a 15000L return pump from sump.

thanks for any help

I think its fine. Typically the return is a bit smaller than the drain and please make sure you add 2 drains!!!! 1 for emergency, in the case the other gets something in it.
