Thoughts on low turn over on a ~260 gallon

[tran383]

I don't want to run a huge pump that will consume a whole lot of energy and might have to deal with micro bubbles. I plan on supplementing circulation with Tunzes and Vortechs. What's the lowest turn over I can get away with, pump recommendations? 1.5" drain but I can probably cut that back to accommodate as well. Thoughts? Thanks.

if you mean flow through sump, then i believe the lowest would be enough to match the pumps on your skimmer.

Tran383,
I don't have that large of a system, but have in the past. I am not into HUGE flow from the sump to the tank, that is why they make tunze and vortechs! I want as much time as I can get for the skimmer to do its job. I have 2 x 1 1/2 drains I am putting about 1000 GPH though it and it is like I am putting 10 gallons per hour, you can EASILY put 1000 GPH at 1 x 1 1/2".

I have a 180, and have about 2X tank turnover. No loud gurgles and no microbubbles.

i also have 2x turnover on my 240, its super quiet

Any chance you guys would have plumbing pictures, esp. of tanks with drilled drains on the back on the tanks rather than below. Thanks.

this is interesting, i'm running a 180 with sump, total water volume - 700ltrs.
i'm useing 2x oceanrunner 3500 returns, theoretically - 7000ltrs per hour, probally more like 4000-5000 per hour because of the height of the return. this is 7 maybe 8 times turnover, sounds like i'd be better off running just the one.

am i right ?

2x-3x is fine. in my 40gal reef i only run 150gph thru my sump/fuge..

if u have a skimmer/fuge down below, u don't want major flow thru it anyway.

your not supposed to rely on your return for flow in your tank. get a return pump to serve the purpose of a return. then get power heads to get the flow u want in the tank.
