Help with ai sol 2nd gen sps brightness levels.

[roberto_lopes]

Hey guys, I have three ai sol super blue 2nd generation sols over my 24 inch deep tank. I'm having some issues trying to figure out what percentages are good for sps. I'm coming from four 54 watt t5's which seem brighter to the eye than the sols, but my upper level acros and Monti's are bleaching. Currently I have all three percentages at 100%, but I think it's to much. I'm kind of scared to go lower though. What percentages do you sol guys use for acros and monitporas.

OK My 350GAL tank have the same deep as yours so you should turn down your lights right now. You will kill them.

In your case I would start with 40% at most and increasing by 10% every 10 days.

I have 12 AI SOL's with all 70 degree optics and at the bottom they STILL put 450-500PAR


Don't forget that the blues on AI SOL are not "just" suplemental ok ? In fact they are responsible by the incredible water penatration. Even with ONLY blues turned 100%, you will get 900 or more PAR at 5" from the water.

I am thinking about swapping out my 250 watt Radium metal halide with Lumenbrite fixtrue for one of the new AI sol Blue's over my 34 gallon max tank.
It' all SPS and would love to save some dolalrs on electric bill. Would also love to lose all the heat generated by the halide.
My current tank is 24 inches wide. Do you guiys think the one full size sol blue would suffice???
I am currently setting up a 36 inch wide 75 gallon bow front. I will then transfer the contents over to the 75 gallon. I thought one sol may still be sufficient for my 75.
What do you guys think?

Thanks!

One AI module might get you by over the 34 but no way over a 75. I would not go lower than one AI module per foot. I have a 180 w/ 6 AI modules over it. I had a module lose a fan, and the module would kick out do to thermal protection. The loss of light is dramatic, and there is no way this would sustain my SPS "in the lifestyle to which they have grown accustomed".
