whats you flow?

[lobsterboy]

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.

[Trigger Man]

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.

[xtreme]

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.

[sphelps]

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

[RuGlu6]

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.

[lobsterboy]

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

crazy flow, 162 times, WOW

[xtreme]

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

[Frenchie]

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.

[Parker]

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

[JDigital]

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

[TheMikey]

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...

[Trigger Man]

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.

[fdiddy]

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

71.2 x turnover.

[Mikee]

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.

[Mrfish55]

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.

[lobsterboy]

Awesome keep it going!!!

[johncody]

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

http://i196.photobucket.com/albums/aa102/johnevans5/IMGP1966.jpg

[mark]

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

[Canadian]

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.

[lorenz0]

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

[phillybean]

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

Mixed reef with mostly SPS

[banditpowdercoat]

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....

[dstasiuk]

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.

[fishytime]

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.

[Rbacchiega]

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

So figure 3750 gph = 41x/hour

[JDigital]

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


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:

[StirCrazy]

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.

Steve

[J.Lloy]

230 Mixed Reef

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

[whatcaneyedo]

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.

[tgoeujon]

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

[fiorano]

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

[FlamesFan]

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

[Captainhemo]

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

[parkinsn]

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 #

[mseepman]

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.

[GreenSpottedPuffer]

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.

[GreenSpottedPuffer]

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

Perhaps I'm delusional but I've noticed more branching and, coupled with more actinic and less white lighting, increased coralline algae growth.

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.

[Johnny Reefer]

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.

Steve

[fkshiu]

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.

[dkcrx]

total of 400 gal
pumps add up to 18950gph
= aprox 47.375

[Myka]

33g LPS only. No sump.

Koralia 2 (600 gph)
MJ1200 (300 gph)

A couple small pumps running hob filter for carbon and PhosBan reactor which according to manufacturer's ratings adds another 300 gph to my tank, but I won't add them in because their flow is very indirect.

900 gph total = 27x turnover.

It's kinda tough to compare turnover and flow because the pumps are rated so differently especially when you compare impeller driven to propeller driven. So it's good everyone is listing the brand and model names. :) My MJ1200 puts out more "flow" than the Koralia 2 even though the Koralia is rated as having double the output of the MJ.

It would be tough to get two MJ1200s in my tank and not have my LPS freak out, which would only be 600 gph total going by manufacturer's rating and only 18x turnover. If I had two Koralia 2s I wouldn't get enough flow, and that would be 1200 gph total or 36x turnover. :lol:

[Aleks]

Wow, I'm apparently inadequate in flow compared to you guys........
15gal breeder style
~700gph flow

47x turnover on 15 full gallons......I have 17lbs rock and 30lbs deep sand bed so probably closer to 12gal water volume, which is 58x turnover.....

[JDigital]

Nothing wrong with that if you are keeping SPS... probably a bit much for LPS/softies though... (58x)

Someone linked to it, and I decided to reply. :lol:

[BlueAbyss]

I wouldn't have found this thread if it hadn't been revived... it's been very informative! I'm aiming for an intermittent random flow in my nano, so this thread has been invaluable. Thanks to everyone who put in their 0.02!

[fishytime]

My post needs editing big time:biggrin:

[pterfloth]

200 gal SPS

2xTunze 6100 = 6800 gph
2xK4 = 2400 gph
1000 gph return

10,200/200 = 51x turnover per hr

Will be adding wavebox

[lobsterboy]

My post needs editing big time:biggrin:

i think everyones tank has changed over the months eh, :lol:

[lobsterboy]

ok, so here;s my updated info

125gallon SPS

last post was: 5900gph, turn over was 47 times per hour

present post: 8123gph, turn over is 65 times per hour

[Zoaelite]

Main Tank (65G)-
2 K4's 1200 GPH each
Ocean Runner 6500- 900 GPH (Calc. @ 700 GPH for head height)
Turn Over= 47X

Frag/ Zoa Tank (60G)
2 K4's 1200 GPH each
Return from main tank 700GPH
Return from fuge 500 GPh (Calc. @ 400 GPh for head height)
Turn Over= 58X

Fuge (27G)
Ocean runner 2000 500 GPh (Calc. @ 400 for head height)
K1- 400 GPH
Turn Over= 33X

Total- 152G, total turn over 7600GPH
Total Turn over Per hour- 50X
Levi

[Oxymoron]

90 gal future sps,
2x Tunze Turbelle 6125 @ 3170 gph ea
600 gph return
= 6940 gph / 77.11 turnover/hr

[SeaHorse_Fanatic]

2 x 2200 Maxijet Mods - 4400gph
Hydor Koralia4 - 1200gph
Hydor Koralia3 - 850gph
Tunze Nanostream 6045 - 1185gph
Sedra9000 - (after head loss) - 500gph

That's 8135 gph on a 210g mixed reef or about 39 times flow.

Anthony

[Lance]

225gal mixed reef:

Reeflo Barracuda (after head loss) = 2500gph
2x MaxiJet 1200's with upgrade = 4200
Korallia 4 = 1200
-----
7900 = aprox 35x turnover



90gal mixed reef:

Eheim 1262 (after head loss) = 500gph
2x Korallia 4 = 2400
-------
2900 = aprox 32x turnover

[Aleks]

Nothing wrong with that if you are keeping SPS... probably a bit much for LPS/softies though... (58x)

Decided to look it up for "official" flow rates of my stuff after your post......

K1 - 400gph
F204- 180gph

580gph/15 = 39x turnover
580gph/12 = 48x turnover

Somehow I thought the K1 was 480gph, and the F204 was 200gph? Anywho, more realistic numbers here now. My Fluval runs empty minus carbon so I'm sure its a little higher than 180 running empty, but who knows...

[Pazil]

I am now at appox. 9500 gph plus the wavebox (not sure how to figure out that water movement).... Running 2 tunze 6105's @ 3434gph each and a dart return at approx 2600 gph. So I guess somewhere around 63 X turnover.

[kien]

Cool. Was curious about other peoples flows and found this thread.

150g
2x tunze 6105 (3434 gph each at full blast)
1x Mag18 return (1300gph; accounting for head loss)
--------
total: 8168 gph ( / 150g ) = ~54x

at night I like to throttle the tunze down to 50% to give the fish a more peaceful rest.

[Oceanic]

Two Tunze streams
1 Maxi Mod w Maxijet 1200
1 MP40W Vortech
1 Tunze Wavebox
1 Mag 9 return pump

11,626 GPH Flow rate :mrgreen:

77.51 times per hour turnover

[globaldesigns]

My DT is 180 gallons with majority of coral being SPS, running the following:

4X Koralia #2's = 600gph each = 2400 gph
1X Vortech MP40W = 3000 gph
2X Returns from AquaMedic Oceanrunner 6500 = 1700 gph total

Total GPH = 7100gph

Total turnover at 39.5X per hour.

[JDigital]

Never did post up for my 30G cube..

MP20 = 2000GPH
Return = 500GPH

2500 / 30G = 83x TO...


Got my 105G coming this week though and this is my plan for that:

MP20 x 2 = 4000gph
Koralia 3 = 850gph
Tunze 6045 = 1200gph
Return = 500gph

6550 / 93.5G (act. water volume in DT) = 70x TO

If the sand stays put with that setup, I might add a 2nd K3 or 6045... :mrgreen:

wow soo much turn over for ur 30 gallon doesnt ur water just go crazy?

[JDigital]

^^ Not really.. water stays in the tank, that's all that matters to me.. That's on a braceless/trimless tank as well. Its also 98% SPS too... thought about adding another K1 or K2, but no point now that my new tank is coming.

[manaf]

oo okay thats good to hear what would be too much flow?

[JDigital]

oo okay thats good to hear what would be too much flow?

When the sand starts to lift into the water column... or the tips of my SPS start to burn.

[shrimpchips]

I'll play!

20g DT
150 gph return (Eheim 1250)
500 - 2000 gph Vortech MP-20
650 - 2150 gph = 33 ~ 108x Turnover

[lobsterboy]

i added a sieo pump rated at 1000 gph. :razz:

so its something like 11,950 gph now.

[es355lucille]

Lobsterboy started this back in 2009......and I find the data very interesting to see the turnover rate in all of your displays. So lets update our data in this link and keep it going. I see that many people in the past that input data have increased the amount of flow in their displays....it will be interesting to see what they look like now.

1. Please give your type of tank: Mixed Reef / SPS / Softies
2. Tank Volume (display only)
3. Pumps and GPH rating
4. Turnover rate (GPH Grand Total / divided by display volume)

Mixed Reef - Sofies and SPS
140 Gallon Display
2 x MP40 Vortech - 6400 gph
Tunze 6055 - 1500 gph
Koralia 3 - 850 gph
Mag 18 return Pump - 900 gph

Total 9650 / 140 = 68.9 X Turnover

[lobsterboy]

nice blast from the past :biggrin:

I am running a whomping 0 times per hour right now :razz:

[es355lucille]

I just want to requote this and when you are back in the game you make sure to add in your flow!! LOL! Nice to hear from you again John. Hope things are well with you! Brad:mrgreen:

1. Please give your type of tank: Mixed Reef
2. Tank Volume 120gal
3. Pumps and GPH rating: Mag 12 (1200gph) and Reeflo Dart (3600gph)
4. Turnover rate: 29x/hr according to the head loss calculator on RC

1. Please give your type of tank: frag trough
2. Tank Volume: 100gal
3. Pumps and GPH rating: Reeflo Dart (3600gph), Mag 3 (300gph), Koralia 4 x2 (1400gph), Koralia 1 x2 (400gph), Iwaki 70 (1500gph @4')
4. Turnover rate... ~60x/hr? after head loss

[abcha0s]

1. Please give your type of tank: Mixed Reef / SPS / Softies
2. Tank Volume (display only)
3. Pumps and GPH rating
4. Turnover rate (GPH Grand Total / divided by display volume)


1. Tank will be SPS dominated. May be somewhat of a mixed reef.
2. 300g
3. 2xTunze 6205, 2xVorTech MP60, 1xTunze Wavebox, 2xEheim 1262 (returns)
4. With all of the pumps running at Maximum flow, the turnover is over 100X

Average turnover is probably somewhere around 60X

It's always interesting to see what other reefers do
here's what i run on my home tank
1) mostly sps tank
2) tank volume is around 440 ish
3.1) reeflo sapper for return(1800 ish after head lost)
3.2) reeflo hammer head for close loop(5900 gph)
3.3) 6 mp40w (19200 gph)
3.4) 8 tunze 6055(11624 gph)
3.5) 2 tunze wave boxes(i think it's around 6400 gph)
4) at max flow about 102x hour

i would think average is around 70x hour:biggrin:

[abcha0s]

4) at max flow about 102x hour


Oh sure - your flow has to be 2 more than mine. :smile:

Having seen your tank, whatever you are doing seems to be working. Maybe I should add another powerhead to get my flow up to 102X? :razz:

40g cube
will be mixed reef
2x Koralia 3= 1700
1x sedra 5000= 400 after headloss
2100 gph = 52.5 x turnover.

200 gallon DD

4 mp40's in master/slave reef crest setup = 12800 gph
water blaster 5000 with head loss = 800 gph

total = 13600 gph or 68x

1. Mixed reef
2. 225g
3. Return pump: Reeflo Barracuda (4500 GPH) with head loss = 2500 GPH via 2
outlet manifold and Vertex Mocean 2000
- 2x MP40 = 5400 GPH
- 2x Turbelle Stream 2 = 4226 GPH
- Korallia EVO 1400 = 1400 GPH
4. Turnover rate: 13,500 GPH for a turnover of 60x



1. SPS dominated
2. 90g
3. Return pump: Eheim 1262 (900 GPH) with head loss = 425 GPH

50gal
softies
2 hk 4s (2400)
1 renea xp 3 (300)
54x turnover

flow in the tank used to be way less 15-20 x and then i rebuilt , im way happier with the tank now with the extra flow .

20G Nano, Mized Reef
Hydor nano coralia - 240G/H
Rio Nano skimmer - 110G/H
Aquaclear 50 - 200G/H
550G/H @ 20G = 27.5X....
(Have been thinking about adding more flow...)

When I first started reading these threads on Canreef and Reef Central I was having issues with cyno algae / turf algae....since I have increased my flow I have no more cyno...and since adjusting my water changes my turf algae is reduced.

When I added the second MP40 to my system it was like a wind storm and it created a lot of added current flow(and some kaotic flow).....my skimmer went nuts for 24hrs....I can say my water clarity is a lot better compared with prior.

1. Mixed Reef
2. 20 Gal Display
3. Mag 7 Return pump with 4' of head loss and ocean motion squirt ~450GPH
4. Turnover rate-- 22.5

Im looking at upping flow after reading this. I like the flow im getting with the motion over what sps I have but I have been thinking that something down low, like maybe an mp10 would move the lower water column very well.

[es355lucille]

Let keep this going. Anyone else have data to add?? Here's what we are looking for:

1. Please give your type of tank: Mixed Reef / SPS / Softies
2. Tank Volume (display only)
3. Pumps and GPH rating (for return after head loss, if you can)
4. Turnover rate (GPH Grand Total / divided by display volume)


Thanks

71G custom cube, barebottom SPS dominated.

1X Red Dragon 8.2 @ 2165G gph @ 60% = 1732 gph
2X MP40Wes @ 3200 gph each @ 80% = 2560 gph each

Total gph = 6852 gph

Total Turnover = 6852/71 = 96.5x Turnover

interestingly enough, if you take the average of everyone's response it does appear to hover around the 40-50x mark :smile:
