The Alkatronic Professional (AT PRO) allows you to easily monitor and adjust KH levels with little to no maintenance on your part, giving you more time to enjoy your healthy, happy aquarium inhabitants.

The AT PRO tests not only KH but also two other parameters that can cause life-threatening situations for residents: pH and temperature. Users can get the latest test results or initiate tests on the go using our voice command function without picking up the phone. The Alkatronic PRO is the first KH controller on the market that tests and controls both marine and freshwater systems.

The Alkatronic Professional is an all-in-one, self-contained product designed to monitor and stabilize alkalinity levels in reef aquarium systems. The Alkatronic automatically corrects any KH deviations by dosing carbonates through its own dosing pump or by activating a Powertronic connection (not included).
