Introducing the AquaMaxx T-NANO Calcium Reactor

AquaMaxx cTech T-Nano Hang-On Calcium Reactors use an up-flow design to mix saltwater, calcium carbonate and CO2 inside a reaction chamber to eliminate the need for daily two-part dosing. Not only will the AquaMaxx T-NANO Calcium Reactor keep your levels balanced, you will no longer have to calculate daily dosages for your tank.

Good things come in small packages

AquaMaxx cTech T-Nano Hang-On Calcium Reactors are computer-precision engineered and utilize the latest aquarium technology to deliver unparalleled performance and value. Despite its small form factor, the T-Nano is rated for aquariums up to 75 gallons.

The new hang-on design allows you to easily hang the T-NANO reactor on your aquarium or in your sump. An effective and convenient inlet filter helps to trap particulates, extends the life of the pump and makes tuning the effluent drip rate as easy as possible. The high-quality pinch value allows for precise effluent control. Simplified inlet and outlet designs also improve efficiency.

With a built-in a pH probe holder, you can easily keep an eye on the pH inside the calcium reactor with a pH monitor or control the CO2 with a pH controller. A CO2 recovery system re-injects excess/unused CO2. This helps lower CO2 usage and minimizes excess CO2 from going back into your aquarium.

Hobbyist-friendly design for quick and easy maintenance

AquaMaxx Calcium Reactors were designed from the ground up with the aquarium hobbyist in mind. The computer precision-cut enclosure makes the reactor look and feel seamless.

Cleaning and maintenance is simple.

The workhorse powering the AquaMaxx cTech T-Nano Hang-On Calcium Reactor is the pump. Each reactor is equipped with an Italian-made Sicce Nano pump. These pumps were chosen specifically for their small size, energy-efficient design and whisper-quiet operation.
