Ok, so I am going with the standard 29 gallon 30x12x18. want it as an SPS dominated mixed reef. Most people have said a 250 watt DE MH, but I have some concerns. what I would really like is the look of a 20k bulb, but the health and growth of a 6500k -10k. So, I figured I would get some T-5 actinics and used either a 10k or 6500 k MH. however, with increasing the wattage with T-5, do I still need a 250K MH? I know it has a better penetrating depth for the 18" height especially since it will be a little ways off the water. But, I am concerned with heat, bleaching, and overall health of corals and tank. I will not have a chiller, so could I go with a 150/175w DE MH with supplemental T-5's and still have an SPS dominated mixed reef?
Thanks
