1 inch & 3/4 inch bulkheads=GPH?


I posted this a little earlier but under a different heading, if I use both on an All Glass Aquarium how much drain will I be getting from both into one pump?
A 1 inch is supposed to be able to handle 600 gph, so a 3/4 is going to be 450 to 500. I would guess at about 1000 gph.
And keep in mind, maxed drain lines tend to be loud, and leave no room for even the slightest snail...er....I mean clog. :)
