I wanted to let everyone know I bought an new odyssea 2x250 mh 4 t5 fixture from aquatraders and got screwed. Received the light 2 of the t5s didnt work. It then took over a month to get anywhere with them. Said they would exchange it and I just called yesterday and now they say they are gonna refund it. Just a warning the lights are crap it would always shock me when I would touch. Also stay away from aquatraders!!
