Reef Factory KH Keeper PlusAutomated Alkalinity Testing with Smart Reef Integration

Take total control of your reef’s most critical parameter. Carbonate hardness (KH/alkalinity) directly dictates coral growth, skeletal development, and pH stability in saltwater aquariums. The Reef Factory KH Keeper Plus provides fully automated, lab-grade alkalinity monitoring—eliminating manual titration and protecting your SPS and LPS corals from dangerous KH swings.

Built with dual ultra-quiet stepper motors and a full-size, laboratory-grade pH probe, the Plus model offers enhanced internal spacing for effortless calibration and maintenance while delivering consistent, highly repeatable measurements accurate to ±0.01 dKH.

Key Features

• Automated Parameter Monitoring: Schedule up to 24 automated tests per day (from 1 to 24 times daily) directly from your mobile device.

• Precision Engineering: Features two high-accuracy stepper motors and a full-sized, lab-grade pH probe for maximum precision.

• Smart Reef Ecosystem Integration: Operates standalone via built-in Wi-Fi—no central computer or external hub required. Fully manageable through the free Smart Reef App (iOS & Android) or web browser.

• Automated Parameter Correction: Pair with Reef Factory Dosing Pumps to automatically adjust liquid dosing regimens based on real-time test results, maintaining perfect stability 24/7.

• Instant Visual Status: Integrated external multi-color LED indicator displays status at a glance:

  • 🔵 Blue: Measurement in progress

  • 🟢 Green: KH within target range

  • 🔴 Red: KH outside target range

• Smart Safety Alarms: Automatic re-testing triggers if readings deviate rapidly. Sends push notifications and email alerts for abnormal KH spikes, drops, or low reagent levels.

• Cost-Effective Testing: Uses concentrated reagent (1:9 dilution ratio with RO/DI water). A single 1L bottle yields an average of ~1,400 tests. Tested sample water can be directed back to the aquarium or routed to waste.
