First off, if you are going to add anything to your tank you need to be testing for it also. There is a coralline algae enhancing suppliment called purple up. However, you need to test ur calcium, alkalinity, ph, etc... It says on the directions not to use if your cal is over 420? i think. I've had the same lr for 2-3 years now and are just starting to get coralline. used purple up once and i have more then what i started w/ on my rock but not on the back glass.
