Deltec PF Calcium Reactor – Advanced Calcium & KH Management
Maintain stable calcium and alkalinity levels in your reef aquarium with the Deltec PF Calcium Reactor. Designed for demanding marine systems, this high-performance reactor continuously dissolves calcium-rich media using CO₂-enriched water, replenishing essential minerals consumed by growing corals and other calcifying organisms.
Particularly beneficial for SPS and LPS reef aquariums, the Deltec PF provides an efficient alternative to frequent manual calcium and alkalinity supplementation.
Innovative Fluidised Media Technology
Unlike conventional calcium reactors, where water can form channels through stationary media, Deltec's fluidised design encourages continuous movement of suitable fine-grained calcium reactor media.
This improves contact between the media and acidic water, helping maximise dissolution efficiency while reducing the accumulation of fine deposits and compacted material.
The result is more effective use of reactor media with less frequent cleaning.
Consistent Calcium and Alkalinity Supplementation
As CO₂ lowers the pH inside the reactor, calcium carbonate media gradually dissolves, releasing calcium and alkalinity into the aquarium water.
This controlled process helps replace minerals consumed by coral growth, supporting skeletal development and long-term reef stability.
Once correctly adjusted, the reactor can provide consistent supplementation as an aquarium's mineral requirements increase.
Designed for Convenient Operation
-
Efficient Recirculation: Encourages thorough mixing of water and calcium reactor media.
-
Fluidised Media: Helps reduce channel formation and improves media utilisation.
-
Easy Maintenance: Accessible construction simplifies media replenishment and routine servicing.
-
Flexible Installation: Suitable models can operate within or outside an aquarium sump.
The reactor can also accommodate suitable conventional larger-grained calcium media, although fluidisation depends on the media selected.
Suitable for Growing Reef Aquariums
Available in several sizes, the Deltec PF range accommodates different aquarium volumes and calcium demands.
Smaller models are ideal for established reef aquariums, while larger versions provide increased media capacity for heavily stocked coral systems.
Why Choose Deltec PF?
Combining efficient media dissolution, dependable circulation and practical maintenance, the Deltec PF offers a professional solution for maintaining calcium and alkalinity in demanding reef aquariums.
Available from Rock ’N’ Critters.
CO₂ equipment, calcium reactor media and a suitable water feed arrangement may need to be purchased separately.
Note: PF509 Does NOT have a PH Probe Holder
