shouldnt need the high outputs for it to be live rock..might want to check your calcium and alk levels...cal should be around 450... how offten do u do water changes and what kind of salt do u use...if u are referring to corraline on the rock i just started supplimenting calcium to my tank andthe coraline is already defenietly improving

You may see some more life come out of your rocks if you add PC's or VHO but whatever coralline you have now is gonna bleach and be replaced by higher light species.
