The Blau Aquaristic Calcium Reactors are one of the best systems for providing an automatic and constant supply of calcium and carbonates.


Easy to install.

Continuous addition of carbonates and calcium.

Gas reinjection system: Total use of injected CO2.

Add on reaction chambers are an optional accessory for the “Calcireactors” that make it possible to use the output water's low pH to dilute more calcium carbonate or other important substances, such as magnesium carbonate.

Furthermore, due to the high concentration of carbonates obtained, they can be used to house iron-based anti-phosphate resins, which consume large quantities of carbonates.
