Calcium Reactors from All Pond Solutions
Aquarium Calcium reactors are best used in marine tanks, working with CO2 and high calcareous media to lower the PH level of the water. A calcium reactor is excellent for replacing magnesium and calcium absorbed by coral and other organisms that exist on a high calcium diet.
A calcium reactor is container filled with calcium carbonate media. When aquarium water passes through the marine calcium reactor, it will give your fish tank a balance of alkalinity by dissolving the calcium carbonate.
