Keep your aquarium water in the very best condition possible using different types of fish reactors available at petco.com. Reactors come in a variety of sizes as well as functions. Understanding the needs of your particular aquarium and tank inhabitants will help you determine which kind of reactor system is right for you.
Some types of fish reactors are designed to add something to your aquarium for the benefit of your tank. These include kalkwasser and calcium reactors, which are ideal for use in reef or marine aquariums.
Calcium reactors combine CO2 (carbon dioxide) and water with some type of calcium-based media, like calcium carbonate (the same chemical we consume in calcium supplements and antacids). The resulting mixture is rich in dissolved calcium which corals and clams need to build their skeletons and shells.
