Quickly and easily check your aquarium's ammonia levels with API AMMONIA TEST STRIPS. 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.

In new aquariums, ammonia should be tested every other day until the ammonia level measures 0 parts per million (ppm) or mg/L. In established aquariums, ammonia should be tested weekly to make sure it is at a safe level. This kit contains 25 test strips and reads 0-6 ppm (mg/L) of ammonia in fresh and saltwater. Just dip and read to measure ammonia in one easy step.
