Say goodbye to chemical test kits and routine dosing! The AquaWiz KH Controller automates your aquarium’s alkalinity (KH) measurement and regulation, without using a single drop of reagent or producing any waste water. Perfect for serious reefers and aquarists who want hands-off stability and advanced monitoring.

Key Features:

• Ultra-Quiet Operation
• Apex-Ready KH to pH Output (BNC Connector)
• pH Analysis for Enhanced Water Quality Insight
• No Frequent Calibration Needed
• Live Website Monitoring + Health Alerts
• Compact, Modern Design with Smartphone Setup
• Accuracy: ± 0.05 dKH | Error Margin: < 0.03 dKH

Smart, Connected & Intuitive

Smartphone App & Web Dashboard: View current KH readings, pH trends, and system health from anywhere.
Real-Time Alerts: Get notified of abnormalities – great peace of mind when traveling.
Minimal Maintenance: Just one manual KH check per month, then update the value online.
No More Bottle Replacements: No more storing or replacing messy reagents.

How It Works:

Takes sample water from the tank
Aerates both tank water and reference solution
Measures pH difference between tank and reference water
Calculates KH using pH
Adjusts KH using built-in dosing pumps

KH values are measured hourly, and adjustments are made in real time to keep your reef aquarium stable.

A game-changing metric that measures the difference between your tank’s real-time pH and the fully aerated reference pH.

• pH above –0.3 = healthy system

• No need for frequent calibration

• Helps diagnose CO₂ levels, skimmer performance, and more
