About Fritz Liquid Test Kits – Alkalinity
Carbonate hardness, or alkalinity (KH), is the measure of both carbonates and bicarbonates present in the water. The KH value of your water is important to know, as the carbonate hardness plays a significant role in the water’s pH and the water’s buffering capacity to keep that pH stable. KH naturally falls over time with the introduction of CO2 and other acids, and nitrification. Reverse osmosis water should be buffered with carbonates before use to raise and maintain KH. Some municipal tap water can have variable KH levels throughout the year and should be checked regularly. In saltwater tanks, KH can be tested to monitor the proper ionic balance when dosing.
Soft water fish, like Discus and other South American cichlids, require stable alkalinity levels to thrive.

The test strips are easy to use and give clear results. I’ve been using this kit for several months to monitor my aquarium’s alkalinity, and it helps me maintain stable water conditions. My discus fish have stayed healthy without any pH fluctuations.
Piers Slater –
I found the instructions straightforward and the results consistent with my other test kits. It’s a reliable tool for checking KH levels in my saltwater tank. The only minor issue is that the reagent solution needs to be stored away from direct sunlight.
