Proper tank maintenance can be as simple as routinely changing out the water and cleaning the substrate from a freshwater tank housing your small pet fish or as complex as using products such as calcium and magnesium in your marine tank. Aquarium live rock acts as a natural biological filter assisting in maintaining the water quality within your marine aquarium. Composed primarily of the calcium carbonate of coral skeletons, it provides an area for beneficial bacteria to thrive and serves as a natural platform for various corals and invertebrates. Aquarium rocks are important aquarium items as they also provide your fish with shelter, which is much needed by small pet fish if sharing a tank with larger pet fish.

In addition to various types of substrate, aquarium rocks, plastic plants and other decorations that can enhance the beauty of your aquarium, adding live plants can help remove organics and oxygenate the water, while providing a natural look and food source for several species. As aquarium live rock contributes to water quality, various other organisms, such as sand sifting starfish, cleaner shrimp, and algae-eating snails naturally help maintain your tank by controlling algae growth and cleaning up uneaten food. Preserve the beauty and water quality of your aquarium and the health of your large and small pet fish with the various rocks, organisms and other products intended for proper tank maintenance.
