Vertex RX-4 Calcium Reactor

Stable parameters are the key to a successful reefscape. Calcium, being utilized by a myriad of oceanic life forms including corals and crustaceans, is amongst the most important of these parameters. As the fifth most abundant ion found in natural saltwater, it is absolutely critical that Calcium is kept at a constant. One of the greatest pieces of equipment aquarists has at their disposal to maintain this parameter is the Calcium Reactor. By dissolving Aragonite-based mediums down to their basic elements, Calcium Reactors allow for a continuous influx of calcium into the system.

Vertex RX-Series Calcium Reactors now bring this potent tool home to you with all the features and qualities you need at values you can easily afford.

Efficient and Easy to Use

Designed for maximum capability, Vertex RX-Series Calcium Reactors feature an advanced recirculating chamber design, allowing for extremely proficient use of media and CO₂.

A large bubble counter makes for easy visibility and effortless adjustments. Fine tuning of flow/effluent is also straight-forward with the high quality Vertex Needle Valve included with each reactor.

Vertex RX-Series Calcium Reactors utilize the exclusive Gas Stable Use (GSU) concept to aggressively dissolve CO2, recycle unused CO2, and extract only reduced CO2 effluent. As a result, Vertex RX-Series Calcium Reactors are more efficient than other available designs.

Robust Construction

Vertex™ RX-Series Calcium Reactors are made to last; being assembled with only high-grade cast acrylic and heavy-duty PVC parts. All Vertex products are rigorously tested for safety, efficiency and reliability.
