I'm getting ready to dremel a hole in my 20 Gal to make way for a sump/fuge. I'm trying to figure out which bulkhead I need. How much flow can a 1" bulkhead handle for overflow? I'm thinking it should be plenty because I'll most likely have 1/2" returns through a sqwd driven by a mag3 or 5 with about 40" of head pressure.
What do you think, should I drill for the 1" or 1.5" bulkhead?
Thx
