POLL: How Much Return Line Flow Do You Run?

[Vivid Creative Aquatics Verified Sponsor]

Just like the title says, how much flow do you run through your return pump and back to the display tank. There are a number of opinions on how much GPH you should (or shouldn’t) run through your filtration systems, but really for this poll, I’m just interested in how much flow, in approx. GPH after head loss, you return to the tank.

Also - In the comments below, tell us what size your tank is and how many outlets the flow is split into. And if you would like, tell us what kind of return pump you are running and if you have a sump or an all-in-one.

After you make a selection in the poll, be sure to tell us how many return lines that flow is split up by and the size of your tank

Darnit - I looked that that for like 10 minutes and knew there was one missing but could not find it - LOL.
Thanks for pointing it out - I added it but now it's out of order... At least it;s there for those that need to select that one.

120g DT with a 55g sump. Sicce Pro 1500 dialed way back. 700-800gph through 2 returns.

I maybe run a little too much, 55 gallon tank a 39 trigger sump with a sicce 7 rated at 1900 an hour wide open. I think it is most likely running about 1000 an hour.

that is a lot of flow - depending on what you're keeping in the tank, it's probably just what you need - how many returns is that flow split into?

Varios6 pump dialed way down
400-500gph estimated return flow

This is great info - keep it coming.
The poll has been updated to allow multiple selections for those that have multiple tanks.

140 DT with another 40 gallons in sump. Jebao dc12000 on setting 2. Guessing around 1200 GPH with 2 returns.

just one return and a gyre on the other side, have a few sps and it has taken awhile but finally the zoo's are used to the flow,and multiplying

Roughly 850 gph in my 200dd. Only one return line. Any more flow raises the water level above center bar due to the lackluster corner overflows. I don't mind however as 850 gph flow through the sump seems about as fast as I would like. I do have 2 250 gyres and a jebao powerhead in the display.

360gph
Single
75 gallon display
Gen x pump soon to be a sicce

Looks like the most popular GPH rates so far is the 400 - 500 and the 1,000, 1,500 GPH rates.

1,375, plus or minus, on a 450 (400 actual gallons of water). So nominally tank turns over thrice an hour. Sump is in the basement, so return line is maximized for net flow - 1 1/2" flex PVC with one flow meter and two 90 degree elbows only with a single output firing directly down behind my rocks. Plenty of powerheads and a CL fir in tank flow. Main pump is an external Panworld 200.

240 gallon DT 55 gallon sump running 2 Sicce Syncra SDC 9.0 at 56% each ( one on steady flow, one on Sharp Break mode ) so approximately 2500 gph total from sump into 4 line locks at 3/4” each.
