lighting switch for the 180

hey there as some of you may know i am doing a complete over haul of my 180 gal reef tank and i have started looking into getting less because the ati powers 8 bulb fixture just draws way to much energy and produces way to much heat for my room i already have 2 kessils a360we fixtures and 1 a160we fixture and i was planning on replacing the t5 fixture with 6 of the galaxy hydro 165 watt leds and i was just wondering how many people have seen good growth and coloration in sps mainly acropora with this light fixture over long term or if anyone thinks i should stick with the t5 and kessil combo and just cut down on photo period maybe someone could give me a good lighting schedule for the kessils which i have a controller for and the t5s for which i have a timer
anyway thanks and happy reefing !!!!
