How to Clean Aquarium Rocks

If you have a good filter and have encouraged the growth of bacteria-eating reef organisms, you will not need to clean your aquarium very often. Filters remove excess bacteria, and bacteria-eating organisms that live in your aquarium eat excess bacteria. Because of the bacteria-eating organisms, you should not clean your aquarium rocks very often. You can purchase the items you'll need at a pet store.
