I have a 26 bow sps tank. I'm currently running a set of T5's on it and everything's growing well, however, as soon as a put a new acro in it immediately browns down. So i'm looking at buying either a 150 or 250 watt HQI Metal Halide Viper Light. I plan to put a 14k Phoenix or a 20k radium bulb in it (double ended). I'm all about overdoing the equipment on my tank and i'd love to put a 250 watt over it but i'm afraid it might be a bit much and bleach my acros. All help appreciated.
