Vertex RX Series Calcium Reactors.
Stable parameters are the key to a successful Reefscape. Calcium, being utilized by a myriad variety 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 as a constant. One of the greatest apparatuses we have at our 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 straightforward 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.
