Hi im looking to switch to t5 lighting on my 100 gallon tank. Its a 6 foot tank thats 18 inches tall... im looking at the current nova extreme pro with 12 39w bulbs with individual reflectors. this would give me a total of 4.68 watts per gallon. i know that watts per gallon is not the best measure but its all i know how to go by. Would this be enough to keep sps corals and clams? Ive heard so much varying info about t5's while doing research, i figured it would be best to just ask outright. Any help would be greatly appreciated.
