Deltec​ Calcium Reactors

Here you will find all Deltec Calcium Reactors with specifications, user manuals and other useful details.
What are calcium reactors?
In marine and reef aquariums, a calcium reactor creates a balance of alkalinity. An acidic solution is produced by injecting carbon dioxide into a chamber with salt water and calcium-rich media. The carbon dioxide lowers the pH by producing a solution high in carbonic acid, and dissolves calcium.
