i have a 50 gallon corner tank. today my POS odyssea metal halide with everything the metal halide and blue lights went out. i thought it was the bulb so i bought a new one and still dont work. so instead of screwing with fixing it i guess im goin to have to buy a new one. what do you recommend? i am new at this and dont know much about the differences. also if you have a light setup for sale let me know what you got and how much. thanks
