What's your return pump turnover

[Capt_Cully]

Not counting internal, redundant flow, what is your turnover from your return pump? (estimated flow after head loss per hour/total system volume)

Thanks

7.25 turnover / hour here

my OR6500 does 1700 gph after about 4ft. of head i'd have to guess about 900 gph so with my 90 gal. 10X....

Averages about 6x tank volume per hour.

Never actually measured it but I estimate the return pump is moving about 550GPH. For the 90g that would be 6 tank volumes per hour. If you include the 30g in the sump then the total volume turnover is just over 4.5. I do plan to upgrade the pump in the near future.

I estimate 7-10x. I could get it higher. I divert just enough flow to my refugium to keep my overflow in the display quiet.

40 breeder with a total at about 50-55 turnover but just my return is 30-35.

215 gallon running 2-Quiet one 4000's at 1000gph each. After head loss I'd guess about 6-7 times tank volume turnover. 90 gallon running 700 gph so after loss I'd guess maybe 4 times tank volume turnover. - Mark

72 gal with mag 9.5.Guessing with headloss Im around 8-10x per hr .(sump return )

I'm at about 4 times. I like a little slower flow through my sump than most but it works out well for me.

 

[Capt_Cully]

That's why I posted. My main concern is my energy consumption, but I want to be sure I'm giving my refugium and Skimmer enough exposure to the tanks main volume. I'm thinking of a Quiet One 4000 coincidentally. But that would only give me 3 or 4x. Its looking like that might suffice considering I'll have an MP 40 and 2 Tunzes rolling in the display.

Any opinion's on sump, fuge, skimmer exposure?

 

[wooddood]

i've always though the turn over rate should be 10 times your tank volume. correct me if i'm wrong.

 

[Capt_Cully]

That's one of those old reef keeping rules of thumb. Total turnover includes any internal pumps too. So not just your return pump. I mean if you count my Vortech and my 2 tunze streams my total turnover will be more like 20x...or beyond.

 

[jerrym21]

my total turnover is around 22x when you add the in tank MP40's and MP10's. I jst like a slower flow through the sump and fuge.

Thanks

note the very first 5 words, not counting internal, redundant flow, thats why i answered the question the way i did.

..hungover...

on the 120 I measured about 345-400 GPH (3X). internal has two MP40's and alternating Koralia Evolution 1150

 

[pascal32]

I suspect most people are lower than they expect. To measure I did a water change out of the display, put measuring tape on the display, and timed how long an inch took, then used a volume calculator. Lastly convert to per hour.

 

[Gravesj1s]

Probably right Blurry,I didnt do an actual just a rough guess.I might do it though just for sake of curiousity.

If I add internals though Im around 50x tank volume per hour.Just using some quick math.

 

[TOM BLEVINS]

my 300 has a 16 time turn over though the sump.

4-6205's in the tank.
