How much flow do i need?

[PegasisR]

I have a total system volume of 139g

My skimmer is a bubble king dc 200

My pump is an ac pump rated for 754gph which im gonna switch to a pump rated for 2200gph

I run filter socks aswell.

My dt has 1 mp40 and a rossmount rated for 1200gph

Im going mixed reed with a good mix of sps, lps and softies, what would be ideal turnover rate for the dt and sump and overall? Thank you

Turnover to the sump, x3-x5 DT volume an hour. DT, x20-x30gph.

Turnover to the sump, x3-x5 DT volume an hour. DT, 20000- 30000gph.

Perfect thank you so much!

Also how would i calculate sump turnover? By multiplying the gallons by turnover rate? Ie. 31g x 5? And then same with dt in thaf calculation?

Sump turn over, 3 to 5 times the DT volume an hour. Display tank, 20-30 times it volume in an hour.

Return pump for a 30 gallon, 30x5= 150 gph.

Display, total power heads water volume in gph. 20x30= 600gph, 30x30= 900gph. For a 30 gallon tank.

Sump, 139x5=695gph.

DT, 139x20=2780gph. 139x30= 4170gph.

I'm running around 40x turnover in my DT on a 6' 125. At 5200gph. It's pretty heavy with SPS and LPS.

Those numbers are also dictated by rock work/aqua scaping and what type of corals you keep.

The idea of a slow turnover to the sump is to allow dwell time with your skimmer and filtration/refugium. Less electricity for return pump.

Corals need lots of water movement, thus the much higher gph out of your powerheads/wave makers.

Oh okay! I have minimal coral and 71lbs of dry rock in my tank, would that change anything?

When the tank is new, lower flow may be enough. As a tank fills with coral, you may need more because of dead spots that coral colonies create.

That is very true! Ill keep an eye on that as the corals grow thank you for your help!
