Hello I have some LR in my tank ,but not any lighting at present (I had a double strip florescent for a while ) ,should i have lighting on it or will it stunt it or not produce anymore coraline purple algea or what could i do to keep it in good shape right now. any reef type solution product, the rock does seem to have just a couple things growing out of it. the tank is really clear no crud on overflow etc. tank is about 4 mths old (72 gal with a sump)
