AquaWiz KH Controller™

Automatic KH Monitoring & Control – No Test Solutions, No Hassle

Maintaining KH levels (alkalinity) in an aquarium can be challenging. The traditional method involves manually mixing an acid like HCl with a water sample and recording the pH change. This process is not only complex and time-consuming—it often needs to be repeated daily.

Say Goodbye to Tedious Testing!

The AquaWiz KH Controller™ revolutionizes this process by automatically measuring and optionally maintaining KH levels in your tank. No test solutions are needed!

All you need is a reference solution—such as your existing tank water with stable alkalinity. This reference water is recycled and reused, producing no wastewater or acid byproducts.

Eco-Friendly & Effortless

• ✅ No test solutions needed

• ✅ No pollutants produced

• ✅ No more shortages of testing chemicals

Smart Features:

• Frequent Measurements: Coral consumes KH at varying rates—measure as often as every hour

• Auto Resume: Automatically resumes after a power outage

• Water Level Control: Monitors and maintains reference water reservoir levels

• Integrated Dosing Pump: Controls KH by dosing KH solution as needed

• KH-to-pH Converter: BNC plug allows KH readings via a standard pH controller

• Calibration-Free Electrode: Uses a specific pH electrode—no calibration required

• Electrode Health Monitoring: Detects electrode aging and alerts you for replacement

• Remote Monitoring:

  • Get email alerts if KH goes out of range

  • View KH history via line chart at www.aquawiz.net

• Custom Intervals: Set measurement intervals from 1 to 6 hours via web interface

• Silent Operation: Enclosed motor and pump, plus sleep timer setting

• User-Friendly Design: Open-lid access for easy installation and maintenance

⚠️ Important: Before using AquaWiz, ensure there is no stray voltage from other devices in your system. Stray voltage can affect performance.
