I recently upgraded from a 29g Biocube with T5 lighting to a 75g tank with a 6 bulb T5 Tek Lite and the problem i am having is that my zoos and even a cyphastrea that i have have lost a lot of color. The water paramaters are good with undetectable nitrates and phosphates.
I am doing 10g water changes weekly and maintaining Magnesium at 1320, Calcium at 420, and DKH at 9, Sg at 1.025. My SPS and fish are doing very well, but the zoos don't look good. They arent dying but the colors are poor. Some zoos like the nuclear green palyys and radioactive dragon eyes look fine, but my blue hornets , Magicians, AOG, Red people eaters are looking faded. They are all on the sandbed. The tank is 21" deep.
I am running GFO in one reactor and carbon in another. My lights where running for 10 hours of the 2 bulb atinic cycle and then the other 4 bulbs come on for 6 of the 10 hours.
So what i am wondering is:
1)Is 10 hours total/6 hours daylight too much? What kind of par would I want and what would be too much?
2) Is the carbon running 24/7 too much? Is it possible stripping something that the zoos need out of the water?
3) Could I have thrown mini-cycle when i switched the tank over and maybe I am just seeing the aftermath now? I kind of doubt that because I think the SPS would have suffered but it has not.
I know this light fixture puts out a lot more light because some SPS that was lacking color ( Palmers Blue Mili, Jose Casas) has colored up after 2-3 weeks in the new tank. But my zoos are on the sandbed and I'm not sure what to do. I have started reducing the daylight cycle to 5 then 4 hours but i really am not sure that it is the light.
Help!!!!!!!!!
