Alkatronic Professional: Your All-In-One Alkalinity Guardian

  • Standalone Alkalinity Controller
  • Monitors KH, pH, and Temperature
  • Compatible with Dosetronic & Powertronic Systems (sold separately)
  • Real-Time Testing & Alerts via Cloud Server

 

Maintaining proper alkalinity (KH) levels is crucial for a stable and healthy marine environment. With the Alkatronic Professional (AT PRO), you can effortlessly monitor and stabilize KH levels in your reef aquarium, ensuring that your alkalinity stays within the recommended range of 7 to 10 dKH. This all-in-one, standalone controller not only manages alkalinity but also monitors pH and temperature, helping to prevent life-threatening parameter fluctuations in your tank.

The AT PRO features high precision stepper motors and ultra-silent DC motors for reliable, low-maintenance operation. It automatically adjusts KH levels by dosing carbonates through its built-in pump or activating a connected Powertronic socket (sold separately). Plus, it’s ready to pair with the Dosetronic dosing system, offering advanced dosing adjustments based on your tank’s specific needs—all without any complicated coding or guesswork.

With the AT PRO’s WiFi connectivity, you can initiate real-time tests, export data, and receive alerts via the Cloud Server function on your iOS or Android device. You can even check the latest test results or start tests using voice commands, giving you more time to enjoy your thriving aquarium.

For freshwater enthusiasts, the Alkatronic Professional is the first KH controller on the market designed to test and control freshwater systems like KOI ponds, planted tanks, and hydroponic setups.
