Saltwater Aquarium Supplies

Providing your saltwater fish with a safe, clean, balanced environment is critical to their health. At PetSmart, we offer a wide range of saltwater aquarium supplies, setup and maintenance products. Water care and conditioning is the first step to a healthy environment for your marine fish and invertebrates such as coral, shrimp and other crustaceans. Test kits and hydrometers can make sure you are keeping your water quality at optimum levels of pH, salinity and hardness, with low nitrite levels at all times. Aquarium salt is a staple of saltwater aquarium care, but can also be used sparingly in freshwater tank setups. Reef salt for marine aquariums contains added calcium and trace elements that mimics natural seawater, encouraging coral growth and invertebrate health. You'll find a wide variety of water additives that help saltwater aquariums and their inhabitants thrive. Because each saltwater setup is unique, you can tailor the supplements you add to the needs of your fish and other aquatic life, such as iodine, strontium and calcium for corals, inverts and symbiotic algae. Don't forget to feed your marine fish properly with our selection of krill, brine shrimp, seaweed and other seafood available in flakes, pellets and frozen cubes. Give the fish in your saltwater aquarium a healthier life with with access to premium substrates and reef salt, plus saltwater concentrates, algaecide, and marine calcium, as well as test kits, protein skimmers and all-inclusive marine reef starter kits.
