Also, consider the obvious; decrease the lighting. I ran a fifty gallon SPS tank for several years with 800 + 440 (1240 total watts) lighting, and several hundred watts for pumps off of two circuits as discussed above. Eventually, when moving to a larger tank I reduced the lighting to to 500 + 220. Honestly, although I was hesitant at first, I've not seen any real difference in growth or color. Sinvce then I've been more power concsious with every aspect of the setup and I am running a 150 on just under 800 watts total.
I've been contemplating 150 MHs in really good reflectors, I think it may work just fine too.
