JBL ProAqua Test GH – General Hardness Test Kit

The JBL ProAqua Test GH is a reliable and accurate test kit designed to measure the general hardness (GH) of aquarium water. Understanding your water’s GH is essential for maintaining a stable aquatic environment that supports healthy fish, shrimp, and aquatic plants.
