hi, i have an AC500 fuge, witha handful of 3 differnt types of algea. im not sure what kind they are. one type is green and stringy, the other is red with some bubble like things on it, and the other is red. is it ok that i dont have any lights on it? i ahvent got any sand for it yet, so i dont have any lights on the fuge. i have had the algea since saturday without any lights. i do have a fixture i could use for the fuge-a 13w screw in power compact. is this ok
