I've been absent lately, mainly due to work and a blog project I'm working on (not related to reefing). My 29g in my office is currently stocked with LPS/SPS corals, and I'm running a 250w coralvue pendant with a 14K phoenix bulb. My thoughts are I'm running too much light. Most of my corals are doing ok, but it seems I'm pushing the upper limit of my lighting, as some corals have started to brown and I'm not getting much growth. I've wanted to do T5 lighting since I started this tank, but 30 inch fixtures have been difficult, if not impossible to come by that have adequate lighting for a LPS/SPS tank. Lo and behold, Catalina has a 30" fixture now, and for a reasonable price $225. http://www.catalinaaquarium.com/product_info.php?cPath=71_136&products_id=1414.
Would this fixture give me enough light, and hopefully not be too much light? I don't know what wattage I should be running for a t5 setup on a 29g tank. Advice will be greatly appreciated. Also, if I decide to get this light, I'll be selling the pendant and the icecap ballast that goes with it. The ballast is less than a year old.
