from what i've read the wavelenght of light probably wouldn't be right to grow corals, cause if it was everyone would use them instead of spending hunderds of $$$ on light setups.
i'm going with a dsb in my new 80 and have put in 55lbs so far of aragonite, but how much ls? I was thinking about 20 lbs and about 120 lbs of lr.

just setting up 80 gal reef tank and would like some input on best way to cycle it. should i get all the lr at once? also some ideas on substrate. my lfs said that 1" to 1 1/2" would do, what do yo think? :)
