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
