whats you flow?

[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

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.

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

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.

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....

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.
