Aquarium Water Care

Water is the key ingredient in any fish tank. The first step in taking care of your aquarium, and giving your fish a home that's clean, safe and healthy, is to make sure their water is at optimum levels. With aquarium water care products available at PetSmart, you can do just that. Whether you have a freshwater or marine environment, our collection of water conditioners and pre-conditioned water, clarifiers, dechlorinators, algae control, beneficial bacteria, aquarium salt and wide range of water supplements can and help you create place where your fish can thrive. Whether you choose to condition and dechlorinate tap water or prefer already conditioned aquarium water, we have what you need. If you need to quickly cycle your tank for new inhabitants, choose a product with beneficial bacteria included so that you can start turning the tank into a bioactive environment for fish, plants and invertebrates. Cloudy aquarium water can be adjusted with a water change, new filter media, a UV sterilizer or water clarifiers to help get rid of suspended particles and dissolved wastes in the water.
