Deltec PF Calcium Reactors

Hand built in Germany Deltec PF Calcium Reactors are an effective way of increasing the KH and calcium in your aquarium and can be used fluidised with a fine calcium media or, more commonly, non-fluidised with 9-15mm grade media such as ROWAlith W.

Four models are available suitable giving an option for saltwater aquariums between 500 and 3000 litres.

Calcium reactors work by adding Carbon Dioxide (CO2) to a small volume of water in a reaction chamber containing a Calcium Carbonate based media, the addition of CO2 reduces the pH inside the unit slowly dissolving the media and liberating KH and calcium. Depending on the media used it can also release other useful elements such as Magnesium. 

Please note: a suitable CO2 bottle, regulator, solenoid and bubble counter will need to be purchased separately to run the reactor.

Should you need to re-purpose the reactor over time Deltec have made the components of their latest reactor ranges universal to allow for the NFP reactor to be easily converted to a PF Calcium Reactor or FR fluidised reactor using additional components, available separately.
