INTRODUCING THE AQUAMAXX CTECH T-3 CALCIUM REACTOR
AquaMaxx cTech T-3 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 cTech T-3Calcium Reactor keep your levels balanced, you will no longer have to calculate daily dosages for your tank. With a seamless body, removable lid for quick media access and a small, space-saving design, the AquaMaxx cTech T-3 Calcium Reactor is truly one-of-a-kind.
Computer-Precision Engineered
AquaMaxx cTech T-3 Calcium Reactors are computer-precision engineered and utilize the latest aquarium technology to deliver unparalleled performance and value. Despite its small form factor and compact footprint, the T-3 is rated for aquariums up to 1000 gallons.
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. The unique pump baffle enclosure helps to minimize noise.
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. Thumbscrews and keyhole flanges allows for easy removal of the lid.
The workhorse powering the AquaMaxx cTech T-3 Calcium Reactor is the pump. Each reactor is equipped with an Italian-made Sicce Syncra 2.0 pump. These pumps were chosen specifically for their small size, energy-efficient design and whisper-quiet operation.

no break in time after hooked up with CO2 set. Unit just works. Solid build, easy setup. Pinch valve somewhat inaccurate but better than most anyway.. Used with Kamoer peristaltic pump and BINGO! Can't be much happier.......

Reactor easy to setup, runs quiet, and has many features including great price point. Reasonable instruction included. Circulation pump is a solid Sicce pump that is easy to service. Bypassed the bubble counter as my regular had it's own, and I didn't like the way to fill the one on the reactor (use a small pump to fill and then a check valve to make sure it doesn't empty- both user supplied). Pinch valve I didn't like either so leave this wide open and put a needle valve on the end (available from Marine Depot). Also have the smaller T-1 version on another tank. Same likes and dislikes, but overall would buy both again. I highly recommend a pH controller as this makes setup much easier- the reactor has a built in port for the probe.Hide
