Fish continually release ammonia into the aquarium through their gills, urine and solid waste. Uneaten food and decaying organic matter also add ammonia to the water. Ammonia is toxic to fish and can cause gill damage, stress and death. Regular testing is recommended because ammonia levels can build quickly due to fish waste and uneaten food. Simply dip the test strip into the water, then compare the results with the precise, easy-to-read color-coded chart to determine if any action should be taken. The chart includes recommendations on how to treat the water and neutralize ammonia. Safe for use in fresh and salt water.

The strips are not nearly as accurate. Just buy the API Freshwater Master Test Kit. In my experience the none of the test strips are not accurate as the drops. **Q: Will this item test for cyanobacteria?** A: No, the ph test kit will not test for cyanobacteria. **Q: Do these measure total amonia (tan) or just free amonia?** A: API Ammonia Test strips reads total ammonia. ## Customer Reviews ### ⭐⭐⭐⭐⭐ They work! *by C***B on March 10, 2026* They work!
