Lighting change

[blondenaso1]

I have been thinking of changing up my lighting on my 55gal. Right now it has 4 110w VHOs and a 175W 12000K Sunburst MH. I want to take off 2 of the VHOs leaving 2 110W actinics and adding another Metal Halide. My question is should I upgrade the 175w ballast to a 250W and put 2 250Ws over it or should I just stick with 2 175s? I know most of you are going to say go with the 2 250s, but is that really necessary? I have several SPS corals that are doing excellent under the current lighting, but I keep them concentrated under the one MH. I would like to be able to place the SPSs anywhere in the tank I want without having heating issues. Oh and by the way, I thik I want to go with the Ushio 10000K bulbs. I am very unhappy with the Sunburst.

I had 14K bulbs then just switch to the 10K bulbs one month ago. Much brighter. You won't believe the difference it makes to the sps. Mine started growing noticibly faster with in 3 weeks and my leather is adjusting just fine.
