Thank you very much Jason. I appreciate the welcome. I did notice that as the tank gets older the white crushed coral is turning brown. I like to ask for advice before i go out and take the one step forward, then 2 steps back. You think it would be a good idea to add 2 more 18w fixtures then? Is there general rule of thumb that some like to follow in terms of light. I seen that for EACH 18w 10000k bulb it is $32, this thing is only like 20" long and 1" diamter and its very expensive. I was not sure if i just put 2 of those in if that would be enough, or if i buy the 2 more fixtures, i can leave the light that is in there, and mix the two (2 ecplise OEM bulbs and 2 coral life 10000k), will that hurt anything? I wish i could get around having to add 2 more fixtures since it would have to be custom, and it is very bright now, but prob not the wavelength i need.

Thanks
