What is the AquaWiz KH Controller Gen 4?

The AquaWiz KH Controller Gen 4 is an automated, reagent-free alkalinity monitor designed for reef aquariums. It helps reef keepers track KH levels automatically without using traditional test kits, reagents, or consumables.

Why alkalinity matters in a reef tank

Stable alkalinity is one of the most important parts of keeping SPS, LPS, and mixed reef aquariums healthy. Sudden KH swings can stress corals and lead to poor growth, color loss, or instability. An automated KH monitor helps reef keepers stay consistent and catch changes early.

Key features

• Reagent-free alkalinity monitoring
• Automated testing every 1 to 6 hours
• Lab-grade pH electrode included
• Optional automatic dosing control
• Remote monitoring and alerts
• Quiet, compact design
• Low long-term operating cost

Who is this for?

The AquaWiz KH Controller Gen 4 is ideal for reef hobbyists keeping SPS-dominant tanks, mixed reefs, coral grow-out systems, and anyone who wants more stable alkalinity with less manual testing.
