The Red Sea KH/Alkalinity Pro Test Kit is an advanced titration test developed for reef aquarists who need precise measurements of carbonate hardness (KH/Alkalinity). Alkalinity is a key parameter in reef aquariums, directly affecting coral calcification, skeletal growth, and the stability of pH levels. This test kit provides highly accurate results, making it ideal for SPS and LPS reef tanks where maintaining stable alkalinity is essential for coral health and vibrant growth.
High Accuracy: Measures KH/Alkalinity with precision up to 0.05 meq/L (0.14 dKH)
Essential for Coral Health: Stable alkalinity ensures strong skeletal development and helps prevent harmful pH fluctuations
Advanced Titration Method: Provides consistent and reliable readings for reef care and dosing adjustments
Complete Kit: Includes reagents, durable glass vial, and an easy-to-use titration syringe
Long-Lasting: Provides up to 75 tests per kit, offering great value for regular water monitoring
Collect a water sample in the provided glass vial
Add the reagents as instructed in the manual
Use the titration syringe until the color change indicates the alkalinity level
Read the result directly from the syringe scale and compare with the provided chart
Record alkalinity levels and adjust dosing as needed with products such as Red Sea Foundation B (KH/Alkalinity Buffer)
Measures 0.05 meq/L (0.14 dKH) increments
Suitable range for reef aquariums: 6.5–8.5 dKH
75 Tests Kit – Includes reagents, glass vial, titration syringe, and instructions
Optimal Range: Maintain alkalinity between 7–8 dKH for stable coral growth
Regular Testing: Check alkalinity 2–3 times per week, especially in SPS-dominated tanks with high consumption rates
Complete Foundation: Use alongside Red Sea Calcium Pro and Magnesium Pro Test Kits for full reef parameter control
Stable Parameters: Avoid large fluctuations in alkalinity, as this can stress or damage corals
Reef Care Program: An essential part of the Red Sea Reef Care Program, helping reef keepers maintain a stable and balanced environment
