JBL PROAQUATEST GH – Water Test Kit for Measuring General Hardness in Aquariums and Garden Ponds
JBL ProAquaTest GH is a professional-grade test kit designed to measure the general hardness (GH) of water in freshwater and marine aquariums as well as garden ponds. GH represents the total concentration of alkaline earth ions—primarily calcium and magnesium—which are vital for maintaining water stability and ensuring the health of fish and aquatic plants.
Water is never just water. Rain and groundwater may contain various dissolved substances depending on soil type and environmental factors. Monitoring GH is particularly important when setting up a new aquarium, performing water changes, or managing delicate species. JBL ProAquaTest GH allows aquarists to conduct fast, accurate, and user-friendly tests from home without requiring specialized equipment.
The kit includes all necessary components: reagent bottles, glass test tubes, dosing syringe, comparison cards, and detailed instructions with helpful tips. Results can be recorded and interpreted easily, and additional reagents can be purchased separately as refills. The test is suitable for values ranging from 1 to over 25 °dH, allowing precise control over water hardness levels.
