JBL KH TEST – Drop Test Kit for Measuring Carbonate Hardness in Freshwater and Marine Aquariums
JBL KH Test Set is a reliable and easy-to-use liquid test kit for determining carbonate hardness (KH) in freshwater and marine aquariums, as well as garden ponds. KH is a crucial parameter that helps stabilize pH, ensuring a healthy aquatic environment for fish, plants, and invertebrates.
The test works via drop titration: simply add the reagent drop by drop into the water sample until the color shifts from blue to yellow. Each drop equals 1 °dKH, making it easy to read and understand, even for beginners. This test provides fast and accurate results, ideal for regular monitoring—especially in CO₂-injected or planted tanks, reef systems, or ponds.
The recommended KH value in freshwater aquariums is between 4 and 8 °dKH, but may vary depending on the species kept. Monitoring KH is essential to avoid dangerous pH swings and to maintain chemical balance.
