what size pump?

[jade2122]

what size pump (gph) can a AGA 65 or 90 take? I know all the manufactured plumbing kits are same size, so how big of a pump can i get?

I have a 2000gph pump on my 44, it takes care of all my flow needs. I've seen darts (3600gph) on 90s, if you are doing sps I would look at a dart maybe a baricuda if you want some serious flow. What size are your drain and return holes?

I would go with a dart. You can't beat the wattage it uses either. Plus you can just throttle it back if you need to.

The manufactured kits can only handle up to about 600 gph per overflow drain. So I wouldn't go higher than 600 gph if you've got one overflow, 1200 if you've got two.

IMO, the return pump should be just enough to return the water to the tank. Most would recommend 5-10x turnover coming from the return. I'd accomplish all other flow with either powerheads or a closed loop system.

you could use the dart as a return and your closed loop.

That 600gph is based on a gravity flow, if you make it a syphon you more than double it, I have 2000gph going through a single 1.5" siphon overflow. What I'm doing on my 375 I'm building is I'm making all the holes in the overflow box drains and just plumbing my returns up behind the tank.

i agree that you can over pump the old school drains by all-glass but the crapy so called durso's won't handle it and the noise will drive you crazy. i'm assuming that they are asking what the standard drain will handle and like inlimbo said don't try to overflow the stock drains if you don't know what going on. and what kind of corals are they doing? that will depend on what they want for total turnover in the tank. 1" pipe will only drain x amount of water and if you induce to 1.25 or 1.50 it will flow more. i had a 125 will dual stock aga drains and i was running 2 mag 24's and they were throttled back 1/4 way and that took 3 days to set so be careful.
