Sorry if this is not correct, however yesterday at the Frag swap in Loveleand, I purchased a used Koralia 3 from vendor and I have no contact info for him hense I asking here. He was also selling a 72" metal halide at his stand. The Power head I bought does not work and I need help contacting this guy. I beleive it was a honest mistake and just hope to trade for one of equal value and size. If you are him or know who he might be, please respond. Also selling a 48" 6 bulb T5 (3mo) old "Chrome". The light has (3) built in timers to control lights and moonlights. The nice thing is it only has 1 power cord. I have used it for about 6 months on my 125 that is 72"x18"x24". Corals look awesome. I am scking $300.00 for light. It was purchased for $600.00 at reef and pond as well as the bulbs. Going to LED;s and no longer need.
