A BTA Endorsement:

API liquid test kits have a proven track record of being accurate, reliable, and robust for testing core parameters and are a BTA pick for general testing.

Test strips are a convenient option for fast, regular checks. However, for diagnosing specific issues, tracking a fish-in cycle, or when maximum accuracy is required, we strongly recommend the precision of the API Liquid Test Kits.
