whats you flow?

[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

[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.

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.

[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.

[J.Lloy]

230 Mixed Reef

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

[Oxymoron]

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

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.
