I'm starting a 22x19x14 frag tank. I think it's around 26g. Would 1 kessil 150w be enough light to grow any SPS? I've stuck w/ metal halides but I'm debating on switching over to LEDs
One could do it depending on rockwork and height you hang it at. You will want it to be higher off the tank in order to cover the tank and not get a lot of shadowing. A lot of that will also depend on your rockwork and its height.
okay, thanks for the info. I just want to make sure that the coverage will be throughout the tank and not just down the center, but i guess i can prop it higher.
