Calcium/Kalk Reactors/CO2

Calcium Reactors and Kalkwasser (kalk) reactors provide an easy way to maintain the calcium levels in your reef aquarium. Without enough calcium, your beloved animals would not achieve optimum health. TB Aquatics offers high quality Calcium Reactors by Reef Octopus, Korallin, and Two Little Fishes. Each Calcium Reactor has a chamber that contains crushed skeleton of high-quality ancient hard corals and Magnesium rock. When the water in your tank goes in contact with these elements, they become loaded with Ca and Mg, just enough to maintain a healthy aquarium. Proven to be ultra durable and efficient, each of the Calcium Reactors and Kalk Reactors we offer comes with a two year warranty.
