I bought 2 T5 dual lighting fixtures took out the 10,000 K bulb and replaced it with a 18,000 K and left the 420/460nm blue in the one with the 18,000 K then the other dual T5 I took out the bulbs that came with it and replaced with one AquaBlue Plus T5 bulb combo of 60:40 of 6,000K/15,000K phosphor blend{says you can grow sps coral with it} and the other bulb with a Power Chrome Actinic Plus bulb that emits 60:40 of 450nm/22,000K combo of deep blue and actinic wavelength of light. Is this enough light for my Hammer coral, Brain and mushrooms? also a clam. My tank is a 28 gallon cube. The 24 inch lights stick out some on both sides like about 3 inches each.

You definately like the blue look. You should be ok with that set-up.

The tank doesn't look blue, but I have another question. Should I put the Actinic lights in one fixture and the whites in the other or just leave well enough alone? This light business has me confused Also can I have SPS corals in with these lights

You might get away with the easier SPS Corals. I would not put actinics in one fixture. One in each unit will suffice. Also, if your going with the higher K range lamps, have you thought of just using all 15k or 18k lamps? And not using Actinics? The actinics don't really put off alot light. (PAR)
