reeferlover · 01/18/2011, 08:07 PM

I receently sent up a 90gal reef ready AGA. The dim 48"18"24h and was worried about not having enough light penetration. i purchased a 6 bulb standard TEK, with ATI bulbs over course

I have mu config like:

BLUE +
12k
BLUE +
12k
PURPLE +
BLUE +

And its too much! I cant believe it. I even have it raised 10" above the tank. AND I AM BLEACHING MY FAVIAS IN THE SAND!!! Thats 30" from the light. My first though was water parameters and wiithout listing them they are good with my calcium a little low around 400. So I purchased to giessmann pure actinics. I have heard these are the best actinics on the market. So my question is what sould my config be and should I move my light back down? I will be giving up a lot of par I know but I have an all LPS tank and dont really want a ton of growth just color. Thanks!

I seriously doubt that is to much light for your tank but if that is the case you can simply raise the light high and gradually lower it back down over the next few weeks, this will acclimate your corals to the light and they will be fine.

I totally agree but the proof is in the pudding. My lower light corals are bleaching. Should I change out one aquablue plus and one aqua special for two giesmann actinics to ease up on the par a little?

Did you light acclimate your corals?

If not, either increase the distance of the light up from the water surface or turn only half the light on and also play with the light periods.

ok. sounds good. I was assuming I would not have to accumlate them 30" from the light and coming from metal halide. Its weird because some are not loosing their color at all. I will turn my light times down a little because my light is blinding me 10" above the tank.
