Put it this way the pic you saw was taken when the LT was in my 12 Gallon Nano cube with 24 watts which is 2 watts per gallon. It is know in my 30 gallon reef tank doing GRRRREAT!!!!!! So I would say not much from my experience. Do you have any pics of your setup even if it looks crappy no big deal we all have to start from somewhere!!!!
I'm in detroit and have a red and green favia, brown and orange acans, leather toadstool, fox coral, cauliflower colony (can't spell correct name pocollia) flor green colony of blastos. Just let me know I can ship as well
