Introducing the brand new, third-generation ATB calcium reactors. This innovated range of our Ca reactors uses the Airstar Return Pumps, renowned for its robustness and durability in environments where abrasive substances such as sand or gravel are very common and can be released from the reaction vessel. Airstar pumps provide sufficient pressure that is essential for the optimum functioning of the calcium reactors. Newly, our reactors are equipped with a removable and maintainable filter screen and can be equipped with a foam filter at extra cost. The lid is designed to be easily removable when replacing the media and cleaning the reactor, and to ensure adequate sealing of the entire system. The reactor also includes a pH sond holder in the lid.

ATTENTION!!!
Thanks to the unique ATB design, the reactor creates a vacuum and draws water from the tank itself and then returns it to the tank after enrichment. Flow velocity can be easily controlled by continuous flow rate control of the reactor pump and integrated ball valve. This saves a significant amount of money that otherwise would have to be invested in the additional pump. Our reactors are made with high precision and tightness and are therefore also suitable for external use outside the filter sump.
