I am just starting out with a 75g tank and want to have a reef tank with anemones, fish and eventually a clam. I am understanding that you need to invest the most into your lighting since this is what keeps everything alive. I am wanting a lighting system that has all lighting in one hood and easy to use. This system also has the lunar lighting. Is this the best I can get or is there something better for my tank. It is 48" lond and 18" deep. My LFS told me I could do a 36" light instead, but I don't think this will get the light to all the places I will eventually have marine life. What sugguestions does everyone have??
