ATB Ca Reactor Super 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.



  • Innovative design of the lid and reactor sieve for easy maintenance and ensuring watertightness
  • Foam filter insert
  • Powerful and durable Airstar pump
  • Input for pH probe in lid
  • Integrated bubble counter
