High performance, quality calcium reactors incorporating a number of great features:

• Unique water intake system using a single integral pump which acts as both a supply and recirculation pump. This allows the V2React Calcium Reactor to be easily installed in any aquarium set-up without the need for a second pump or any modifications to existing pipework.

Integral bubble counter which enables easy, measurable dosing of CO2 to the Calcium Reactor.

• pH probe holder which accepts all standard sizes of pH probes and enables the Calcium Reactor to be used in conjunction with pH monitors or controllers for more advanced aquarium set-ups.

• CO2 pressure regulator which allows for the precise control, adjustment and dosage of CO2 to the V2React Calcium Reactor.

• Ideally used with TMC Coarse Coral Gravel (not supplied) but can also be used with other similar types of filter media.

• 12 month guarantee.
