T5's don't grow sps corals lol. Yeah right tell that to the 100,000 amazing sps reefs grown by T5's. T5's will cover way more coral tissue so will not get the dead spots on the underneath of corals. You can control the spectrum much easier, with less heat issues and the ability to go dusk / dawn. The right 8 bulb t5 fixture would absolutly grow sps faster with better growth then 2 175w or even 2 250w hallides. The only thing halides have over T5 is shimmer, which you can get from adding a couple leds. MH are great but they just dont compare to the new t5 fixtures and bulbs coming out. Why in the world would you want to run a chiller on a reef tank. its just one more thing to worry about that might crash and it wastes energy and space.
