I have my lights hung about 12" from the water's surface on my 48"x24"x24" tank. When I got my lights I checked the par with the LFS par meter and levels were similar as yours, with all channels at 100%. I currently run channel one at 70% channel two and three at 100%, and channel 4 at 30%. I have 2 v3+ compact fixtures.Hi,I have been running 3x3+ over an 8ftx2ft x2ft sps and lps tank for 6 months now replacing 400w halides,I have had no problems other than occasional wi-fi loss(my provider) light need time reset but hold program.
I am running at 100% all channels for 5 hours with two hour ramp morning and 4 hour ramp down in the evening.
Colour to my eye is very nice to look at bright with a blue cast,good spread,I can see no shadow ar dico effect tank is quite open though.
They are at 10 inches off water line.
Lps colour and growth has been good ,colour on sps also good but growth is very slow compared with the halides obviously this could be down to
Coral acclimatisation or other factors.
I would not go back.
The only complaint I woul make is other users do not seem to give settings or height info to make a comparison or for guide I have followed lots of threads and tried various searches.orpek info is fun but peer info would be great.
My par is 450 surface,250-300 mid way,100-120 on sand at 23 inches deep.this with an old quantum meter so may be low in blue response.
Maxwell,it would be great to see your settings as your tank is something to behold,been on your build threads but I don't think I have seen
Them.
