whats you flow?

[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

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.

[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.

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.

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.
