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.
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.

Setup review

The cylinder holds about 2 to 2.5 bags (4kg bags of reborn media).

I had a bit of trouble getting the Sicce pump to seal and it leaked more than a few times before I could set the seal properly and stop the leak. If the inlet and outlet Sicce recirculation pump connections aren't perfectly aligned, or you don't orient the fittings correctly, it will leak. This is likely because the Sicce pump has a rather flimsy impellor bracket to hold the intake line to the pump.

The lid on the reactor needed to be tightened hard to prevent leakage from the top. I bought a Neptune PMUMP to feed the system, but it was too strong and caused the secondary C02 chamber (separate purchase) to leak from the pressure. I switched to a more basic low volume feed pump.

I had a Korralin reactor before. The Aquamaxx reactor keeps a constant visible flow of CO2 in circulation. You'll see tones of bubbles running through the chamber and the integrated lid inlet and outlet lines. In contrast, a Korralin reactor would not have any visible bubbles. The box around the Sicce pump is a bit weird and I removed it, as I didn't see the purpose.

This system also restricts the output of reactor at the inlet side of the system as opposed to the output. So far, output flow seems consistent.
