ATB Ca Reactor Nano Size

Introducing a completely new, third-generation ATB Calcium Reactor. This innovated range of our Ca reactors uses the Airstar return pump, renowned for its robustness and durability in environments, where abrasive substances such as sand or small stones are very common and can escape from the reaction vessel. Airstar pumps provide sufficient pressure that is necessary for the optimum functioning of calcium reactors. Our reactors are newly equipped with an easily removable and maintainable filter screen and a foam filter. The lid is designed to be easily removable, when replacing the media and cleaning the reactor, and to ensure sufficient tightness of the whole system. Part of the reactor is also port for pH sond in the lid.


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.

ATB set and bottle for connection of the Ca reactor to CO2

Notes: Try to avoid dispensing high iodine content near the white PVC parts Never remove calcium water from the reactor directly to the pumps. Doing so may cause their damage, due to calcium deposition.

WATCH OUT for replicas of the original and patented ATB design.
