The Aquaforest Alkalinity Test Pro Box is a professional-grade titration test kit designed to measure carbonate hardness (KH) in marine aquariums. Alkalinity plays a critical role in stabilizing pH and supporting coral calcification, making accurate monitoring essential for reef health. This kit provides precise results, enabling aquarists to maintain stable water chemistry and create the ideal environment for coral growth and vitality.
High Precision: Measures alkalinity with accuracy up to 0.1 dKH
Reliable Titration Method: Ensures consistent and repeatable results
Supports Coral Health: Helps maintain stable carbonate levels for strong skeletal growth in SPS and LPS corals
Easy-to-Use: Clear instructions and simple step-by-step testing process
Professional Quality: Trusted by aquarists worldwide for reef maintenance
Collect a water sample in the provided vial
Add reagents according to the step-by-step instructions
Titrate until the color change indicates the alkalinity endpoint
Compare results to the provided chart to determine KH value
Adjust dosing as needed to maintain recommended levels
Measurement accuracy: 0.1 dKH
Recommended range for reef aquariums: 7–9 dKH
Box Set – Includes all reagents, testing vial, titration syringe, and instructions (sufficient for up to ~78 tests depending on water KH level)
Test Regularly: Check alkalinity 2–3 times per week, especially in systems with fast-growing SPS corals
Maintain Stability: Keep KH between 7–9 dKH to prevent pH swings and promote coral health
Use with Other Kits: Combine with Aquaforest Calcium Test Pro and Magnesium Test Pro for complete reef chemistry monitoring
Pair with Supplements: For precise adjustments, use Aquaforest KH Buffer or Component 1+2+3+ system
