API High Range pH Test Kit for Freshwater and Saltwater Aquarium

If you keep marine fish, African cichlids, or you are working with very alkaline tap water, you already know that knowing your numbers matters. The API High Range pH Test Kit is made for exactly those tanks, giving you a clear reading where the pH runs higher than the average community aquarium. It is designed for both freshwater and saltwater setups, so one kit can follow your fish wherever your hobby takes you.

• Reads pH within the high range of 7.4 to 8.8, the window that matters most for marine tanks, African cichlid tanks, and very alkaline tap water.
• Built for both freshwater and saltwater aquariums, so you can use it across different tanks in your home.
• Helps you measure pH changes over time, so you can spot shifts before they affect your fish.
• Each kit includes enough solution for 250 tests, giving you a long runway of regular monitoring.
• Made by API, a familiar name in aquarium water care, so it slots right into a routine many hobbyists already trust.
• Keeps your testing focused on the high end of the scale, instead of guessing with a general-range kit.
• Simple to fold into a weekly or biweekly check so your readings stay consistent.
• Supports the kind of steady, informed care that keeps an alkaline aquarium on an even keel.
• Useful whether you are setting up a new high-pH tank or maintaining an established one.

Testing the water is one of the most caring habits you can build as an aquarist, because your fish cannot tell you when something is off. With 250 tests in every kit and a range tuned to higher-pH environments, this API kit makes it easy to keep an eye on your marine, cichlid, or alkaline tap water aquarium. Add it to your shelf, set a regular testing rhythm, and let the numbers help you give your fish a stable home.
