I'm wanting to find out what others thoughts are on what ballast I should run for a 250w de 14k Phoenix in a reef optix 3+ reflector. I was looking at the aqua medic reeflex cube, because I like the price point and some say that magnetic ballast is the was to go. I have never owned Mh lighting and would appreciate any opinions. It is all just a little confusing to me as I continue to research. Thanks
