whats you flow?
 

Hey Guys, and Gals., it would be awesome if everyone participated in this thread.

I want to know whats your disply tank size and how much GPH is flowing in your power heads combined.

I can start.

125 gallon, SPS, with 5900 gph,= 47.2 x per hour.

around 125 gallon, 4 k4's (4800), and a Mag 18 return (1800) so grand total of 6600 gph. I assume the mag losses around 600gph due to plumbing so 6000 gph (around 48 x per hour) when everything is running (around 3-4 hours a day) and 3600 gph (around 28.8 x per hour) when the wavemaker is turning 2 K4s on and the other 2 off in a 45 second rotating cycle.

In my 125gal I have around 7400 GPH. (Mag18 return, 2x Koralia 4, 1x Koralia 3 and 2x Vortech MP40W's running about 80% on Lagoon Mode) for about 60x turnover per hour.

SPS Main Display 130gal with a super rough guess at 9340GPH = 72x TO

60 gal tank
one TUNZE 6100=Flow Rate: 792-3434 GPH
two TUNZE 6550=Flow Rate: 264-1453 GPH
one 6212 = Flow Rate: 792-3434 GPH (now out of the system)
all are on TUNZE multi controller

combined max flow = 9774 or 162.9 x hr turn over, wich is nothing compare the the real ocean swell over the reef top.

Great feed back everyone, also lets add if its, a softy, SPS, or mixed tank.

crazy flow, 162 times, WOW

My reef is SPS dominated. And my guess of 60x is on the conservative side, and I am considering adding more flow still.

220 gallon mixed tank

2x 750 gph return pumps = 1500
3x Koralia 4s (1200 gph) = 3600

Total = 5100 gph

5100 / 220 = 23 x

I will be adding a vortech pump as soon as I can find a good deal.

90 Gallon:
1 ea K4 - 1200 gph
2 ea Maxi-Mod 2000 GPH ea approx
3200 GPH Total

265 Gallon:
3 Darts 3600 GPH ea
10,800 GPH minus head loss

75 Gallon, Mixed Reef
1200 Return + 2100 CL = 3300gph
44x turnover..

1 x Koralia 1 in the Nano (400 GPH) and a HOB Filter putting out a bit more in the 15G

27X turnover...

I have another Koralia 1 but not sure if I should put it in or not...

As to what is in there for corals;
9 SPS large colonies, 12 larger branching SPS frags, 3 types of zoa colonies, riccordia colony, Torch colony, Frogspawn colony, Xienia colony 3 GSP colonies.
So a mix of everything, and now I come to realize why i have been having to up my dosing of Calcium and DKH consistantly.
The tank again,
around 125 gallon, 4 k4's (4800), and a Mag 18 return (1800) so grand total of 6600 gph. I assume the mag losses around 600gph due to plumbing so 6000 gph (around 48 x per hour) when everything is running (around 3-4 hours a day) and 3600 gph (around 28.8 x per hour) when the wavemaker is turning 2 K4s on and the other 2 off in a 45 second rotating cycle.

Very lightly stocked softy 40g tank:
2x koralia 4 - 2400 gph
450 gph return
2850 gph

71.2 x turnover.

90g
2x K4's - 2400gph
1x Vortech MP40W - 3000gph
Eheim 1262

roughly 67x

I plan on switching the 2 K4's out with another Vortech and maybe leave a small K4 in the back but didnt see any good deals on boxing day for the Vortech's sadly.

So how does one calculate the flow for a wavebox? It moves the entire volume of the tank every cycle (1-2sec.)
not counting the wavebox I have
2x return pumps @1100gph ea.=2200
K-4 =1200
k-3 x 2@850=1700
Total 5100gph in 300 gal tank = 17 times turnover + wavebox.
Don't want to increase flow much more as I think I am pushing the limit for the bubble coral, all sps are doing fine as is.

Awesome keep it going!!!

215 Gallon Softy

2 - 750 GPH return pumps = 1500 GPH
2 Koralia 4 = 2400 GPH
1 Aqua Clear 110 = 900 GPH
1 Tunze Turbelle Stream Pump on Control = 3100 GPH


TOTAL GPH = 7,900 / 215 = 37x

145g mixed reef. Dart on CL, Barracuda return, about 32x.

30g (24 x 18 x 18) tank SPS Dedicated

2 x modified Tunze Nanostreams at ~ 1200GPH each
1 x Vortech MP20 at ~2000GPH (when at max flow)
1 x return at ~ 200GPH

Grand total: 4600GPH for 153 x turnover


The other day I decided this was too much flow as I watched my m. digitatas grow downwards and most of my SPS do minimal branching and only encrust. So I unhooked the 2 x Tunze Nanostreams and am just running the return and MP20. Perhaps I'm delusional but I've noticed more branching and, coupled with more actinic and less white lighting, increased coralline algae growth.

60gal (48x16x18)

2 x Tunze nanostream 6055 at 60% (so about 1744GPH)
2x return at about 400GPH each

So right now about 2544GPH right now 42 x turnover

probably will turn them up a bit down the road

500 GPH Return + 3000 GPH Closed Loop = 3500 GPH = 46.6 Turn Over

Mixed reef with mostly SPS

45 gallon softie.
1 Koralia 2 600gph
1 Quiet one 3000 600gph
2 mag 350 200gph est with pipe losses. probibally less flow

1400gph 31x/hr Hmm and I still have detrritus settling....

135 gal mixed reef (minimal SPS).
OM 4 Way closed loop w/3600 gph, 1200 gph return (both minus head loss) for approximately 4000 gph - 30x plus Tunze wavebox.

110g mixed reef 2 tunze 6055s on multi-controller, vortech MP40 1 koralia 4, 1 koralia 2 and a conservative 600gph on the return. 9000ish gph, 82x turnover.

90 gallon future mixed tank
Koralia 4, 2x koralia 3, Quietone 4000HH Return with approx 5ft of headloss.

So figure 3750 gph = 41x/hour

I bet your loosing more than just 100GPH head loss on your return man. I loose close to 500gph on my 75G with the OR6500. :wink:

my old tank was 94 gal, and between a couple tunze, couple Mak4's, couple mags, i was pushing 13536gph, for a turn ove of about 144x.

My new tank will shoot for about 125X in a 27 gal tank.

230 Mixed Reef

Running only a Sequence Hammerhead 5800gph, minus 6 to 8 feet of head.

120gal with mag 12 running spray bar: 1200gph and Sequence Dart return providing around 1500gph after head loss through an Oceans Motions. So 22.5x per hour.

110 gallon mixed reef
1x koralia nano @ 240 gph
2x koralia 3 @ 850 = 1700 gph
1x koralia 4 @ 1200 gph
1x koralia magnum 8 @ 3250 gph
mag 9.5 return @ 950 gph - 4' head =800 gph
total = 7190
roughly 65x turnover i think

2 tunze nano stream 6025 and 2 6045 and my return of 1200 gph ending up around 38 x turnover.
and this tank is on its way to becoming an sps tank lol

90g Mixed reef (7 SPS colonies and 5 frags)

2x koralia nano @ 240 gph
2x koralia 3 @ 850 = 1700 gph
Reeflow Snapper return @ 2600 gph - plumming roughly 2100?

total = 4040

should be somewhere around 44x turnover

55 Gal Mixed Reef

Quiet One 4000 Retrurn =800 (3' head)
Koralia 3= 850
Koralia 2= 650
Koralia 1= 400
MJ 1200 = 147 (295 x 50%, on wavemaker)

total 2847 , approx 52X / hr

I have a 120g (48"x24"x24") SPS dominated reef, im running the following;

Mag 18 return (est 1250gph)
2- Koralia 4's
1- Koralia 3
2- Vortech mp40w's, set about 80% on lagoon mode

For an estimated 9500 gph or 80x turn over. I also have 2 aqua clear powerheads buried at the back of my rock work that im not counting as i dont recall the model #

70G mixed tank.
1 x Koralia 4 (1200gph)
1 x Koralia 3 (850gph)
1 x Koralia 2 (600gph)
1 x QO return pump (about 300gph after head loss)

Total 2950gph / 70g = 42x turnover. I've thought about more but whenever I add it, mushrooms start letting go throughout the tank and create a real mess.

Mixed reef (sps dominated) 98x turnover with maxijet mods, a K4 mod and return pump. May add a wavebox or vortech to add some much needed random and back and forth flow.

Not delusional at all...I have noticed the exact same thing many times. I bought a nice sized colony of a green acro a few months back. Decided I really like it and so I fragged it a few times to put in different spots in the tank (the tank has years to go before its grown in anyways, so fragging colonies is not a big deal). I have noticed that two of the pieces I put in very high flow have only encrusted while the piece I put in a very, very low flow area is growing like a weed, straight up. The one growing the fastest gets just random flow from different directions because its right in an area where flow from both sides of the tank meet. Says a lot about flow...less but more random has been very good for this acro. Same thing with the digis I have all over the tank. Ones in low flow grow much faster and higher while the ones in high flow grow thicker and diagonally almost.

180g LPS and softies.

2 Tunze 6100. 6340gph.
2 MaxiJet 1200. 590gph.
Mag 18 return. 766gph, estimated after head loss.
Total 7696gph ~ 43x turnover/h
...but, I recently decided to cut back so I put the Tunzes on timers. Six hours on, 6 off. And opposite each other. So...with at least one Tunze off all the time, flow is now...
4526gph ~ 25x/hour.

as you both have seen there is a lot more to flow than just the amount, you also have to achieve a masive water movment with out blasting with a slight up welling. I had to fiddle with mine for about 2 months to get the growth and shape I wanted and if you have sane forget it as now you are putting that flow in the top 1/2 of the tank so you are realy doubling it in that area.

even with a 144X turnover in my tank, you could put your had anywhere (aside from directly infront of the pumps) and only feel a gentle current anywhere in the tank.

Tunze 6100 (~3,000 gph) alternating with a modified Tunze 6055 (~1,800+ gph)
Eheim 1260 return (~250 gph after head loss etc).
Wavebox

So at most about 3,250 gph of "primary" flow at any one time.

120 gallon display = ~27 times turnover.

Mixed reef on a Gyre flow pattern.
