Saint Louis! WooHoo! Depends on the type of algae you want to get rid of. Nutrient export is the best way to rid you tank of it, imo. RO/DI water, fuge w/macro, feed less. All things that will help in the long run. I've had success with Astreas, Nassarius, and Cerith. Not necessarily all for algae, but they do a good job with the cleanup.
How old is the tank?
