I just set up my 90 Gal. Its been fine looks great everthing looks good, My local fish store (wont name a name?) is telling me that my current lights are no way strong enough to get any good corals? I did a;lot of research and i thought i made the right decision? But he is telling me different. I dont want halides do to a chiller..... and another $2,000. for the entire setup... also he said that i should switch to all white bulbs for maximum out put??? I currently have 3 white 2 blue and 1 purple????? Any advice will be greatly appreciated.... Im going to post some pics in a few . Thanks all.....
