How much GPH ???

[RonMidtownStomp]

Alright, so my turnover into my display tank is probably a bit higher than advertised, but certainly not as much as if I'd hooked an Eheim 1262 up to it directly and let it run full blast. What I should do is go make sure I'm turning over enough water into my skimmer chamber.

yep, as long as you are not drain feeding a skimmer, that is sufficient turnover from tank to sump.

Not drain feeding Mark .

Hey Ferdie

It sounds like you have the herbie drain right. Two drains, the shorter one restricted and submerged, the taller one a little above the water line.

I'm with Mark on the tank-sump flow rate, 500-1K GPH is fine. I use a 1262 on my 300g. If you have chaeto or rubble in your sump, like I do, you may want to add a power head down there to keep it from fouling. I run the exhaust from my skimmer to the other side of the sump so the water flows across the rubble bed before it re-enter's the skimmer or exits the sump.

If you have an external skimmer that draws from your sump than your flow rate through you sump should be at least as high as the manuf recommended flow rate through the skimmer. If the flow rate through the sump is significatnly lower than the flow rate through the skimmer than you'll have very clean sump water and not so clean tank water. In theory this relationship is true for in-sump skimmers too but most don't publish their water flow rates. Its usually about 2/3 the skimmer pump's water flow rate.

Yes Brian ,
Herbie drain it is. Am planning to feed calcium reactor , media reactor and maybe chiller on my return line. I was thinking 1262 is not enough if everything is running?

Hey Ferdie

I'd run the return through the chiller then back to the tank. Otherwise, the sump-tank flow rate is too low.
