Turn Over Rates For SPS

[ReeferMonkey]

I have a Seio 620 in my Minibow 7. When it first went it it stripped the flesh off of a brand new acro colony. I throttled it down and it's been all gravy ever since. Now that it's slimed up I may crank it back up.

One 620 in a 15g should be fine, just don't aim it directly at corals.



edit:
Merv, as far as natural current Harry is talking about them being on a wavemaker....

Wow, looks like I need to add another Tunze Steam to my tank.
Compared to the turnover rates posted above mine seems like nothing.

 

[GunMoto]

SunnyX - As long as your SPS corals seem happy, then you're fine. I'm not aware of any standard minumum turnover rate for SPS corals. I think a adding a second 6100 is worth a shot, given you have the available resources.

Thanks concept3 and reefermonkey, I'll give the seio a whirl, it's cheaper than the other set up anyway. I'll get a turnover rate of 41.3 times, which should be plenty. Thanks everyone!

Now you guys got me thinking hard!

Now you guys got me thinking hard!

Im planning my next tank with VISIO 60 x 18 x 23 glass (100gallon)
using OM 4 way on a Sequence pump (approx 2600gph) [closed loop]
and a
Reeflo Tarpoon split into 2 using an Eductors (approx 1500gph) [return]

now turn over rate for that is

42x

based on how you guys set up your tank... it seems like Im way behind the usual.

I have to be conservative for pumps since I need to save electricity and i hate the looks of power heads and wires on the display tank.

Is 42x good enough?

I may add a SEIO 1100 thru the UPS for safety sake on power outs

 

[bond007069]

I have 41 X, mine looks fine.

I may add some seio 1500 also

 

[DrBDC]

2Xseio 1500's
1 mag9.5 with head loss can't be over 600 because I only have a 1inch return.

3600/70 = 51.42X turnover.

 

[angelfishlover]

I'm gonna have a

Seio-820
3 Maxi Jet 1200's
App 1500 Powerhead

equals up to about 25X

It's not how big it is, it's what you do with it

Seriously, late last summer I removed the closed loop I ran in favor of a Seio. As it allowed me to better direct flow to problem areas - it seemed like it improved my tank even while removing 8x flow.

---

Currently my 58g has:
Return pump ... 500gph
6060 stream ... 1800gph
Seio 820 .... 820 gph
MJ1200 ... 295 gph
------ 3415 gph total flow ... about 58x

 

[smokez01]

i have two Seio 620's

with about ~600gph from my return pump

which is about 73.6x turn over rate

and im thinking about switching one of the seio 620's for a 1100

i duno why, but i dont think the 620's are enough, i think its the way the tank is, its like a tall tank, not shallow, i def think tall tanks are harder to get the right flow, cus in some spots my sps seem so calm, i love it when i see their polyps go nuts

but, on the other hand, in a 144 half round tank i take care of at work, there is about 11x the TO, the only flow is one mag 9.5, and a rio 600 behind the rocks, the other guys at work think that that flow is more than enough, i want to add two seio 1100's to each corner, and im telling him that whats in there isnt enough, but, whatever, hes one of the managers so i cant really say much

but the weird thing is, the sps that i have in there are happy, with full PE, its just the polyps dont go nuts, it ****es me off cus they seem happy and colored in a chill tank, and in my 73x tank i want more =/

 

[jiggy]

120g
3 seio 2600s
mag 9.5 return
350g return from phos reactor

= 75.83 turnover

 

[dphins]

Planning 40 gallon breeder with 4 6100 tunze=317.5
Is this enough for sps?

 

[Purple Haze]

60gal cube

Return 5-600gph
2- Maxi's under rockwork 400gph
2- 1500's
---------------------------
4000gph/50gal tank volume=80 times. Of course, not exact or taking into account total water volume. (about 65gal total)

 

[MacnReef]

58g with a Mag9.5 return, a SEIO 1100 and a SEIO 1500.

Total flow approx. 3300 gph.

3300/58 = 56.89 turn overs per hour

I have to say, this is a ton of flow in my tank. Not sure if it is just because I am only dealing with a 36x18" tank or what. But nothing settles in this tank.

[ONEMANBAND]

90 gallon with sequence dart closed loop, mag 9.5 return, 3 mag 7's across the bottom to keep everthing mixed up. No wavermaker, going to add either oceansmotions or sea swirl type unit one of these days.

 

[broe33]

genx pcx55hp 1141x5 (theoretical penductor multiplier)
seio 1500
seio 600
104x turnover

i had a tunze in there also but i couldn't get water to stop blowing out of the tank. i had to drill the teeth lower in my overflow to accommodate the genx pump.

 

[xtrstangx]

My 120g is gonna have a Sequence Dart on CL, 2 Seio 820's, about 500-700 GPH from my return (GenX PCX-40), and a minimum of 2 Maxi-jet 1200 in the rockwork. Thats about 48.6x turnover. May end up getting another Seio for the front of the tank or perhaps an Icecap Vortech when they come out?

 

[ReeferMonkey]

20L w/ MJ1200 (feeding Remora), Seio 820 and Seio 620
87X

When I up the 620 to another 820,
97X

Sadly, this isn't really enough. Also, the calcs dont' take into acount friction loss, slime coat, pump funk, etc.

 

[Weatherman]

120g

Two eductors, driven by an Iwaki 55: 700 x 5 = 3500 gph
(backpressure from the eductors really throttle back the flow through the pump, but they make up for it by increasing flow in the tank).

Single 6000 Tunze: Peak flow 1850 gph

44.6 x


Considering how much my four, evil damsels get bounced around, I think things are in pretty good shape.

 

[Floridiot]

150 Gal.

2 ea Tunze 6080 = 4500 GPH
Iwaki 30RLT return = 800 GPH
Tunze Wavebox = ???

Does anyone know how to calculate Wavebox flow?

I got 35X constant (not peak) + wavebox.

I plan on adding another 6080 soon which would give me 50X constant + wavebox.
