90 Gallon Plumbing

[FishBoss]

Hey guys I am planning on setting up a 90 gallon reef tank but i am confused on what size my plumbing should be for it. I have read that you should have 10x the water of your dt going through your sump and that would be 900 gallons. but a one inch bulk head doesnt produce that much so what should i do is a one inch bulk head enough?

10x is quite high.....3-5 times the tank size is more than adequate.

I prefer somewhere in the 5 to 8 times range. A 1" drain line (and a second emergency 1" drain line) would work well along with two 3/4" returns.
