I have a fuge moded AC110, a 240nano Koralia, and a Fluval E series 50w Heater. Im trying to get a grasp on LED v.s. well everything else, is the Marineland double bright LED better then Sunlight Supply New Wave 4 Bulb T5 ?? I would just like to know the best light so I too can have an amazing display of corals like many before me. Thanks for your time, feel free to give me some other adive as well
