API Ammonia Test Strips

Reads ammonia only, 0 to 6 ppm.

Dip strips that read ammonia from 0 to 6 ppm in fresh or salt water.

Consider: One reading, ammonia, per strip. A liquid kit reads a wider range, up to 8 ppm in API’s.

How to read it
Dip the strip in the tank water and compare it with the color chart, which also says what to do about a high reading.

Before choosing this model

  • Pair it with a nitrite test while a new tank cycles: this strip reads ammonia only.

In a new tank the readings that matter most are ammonia and nitrite, so check the kit reads both, or add a test that does: see how to test your water.

Included items & upkeep

  • 25 test strips
  • color chart with treatment advice

Plan for the routine work

  • In a new tank, test every other day until ammonia reads 0 ppm; in an established tank, test weekly, as API advises.

Check the use-by date printed on the pack before you trust a reading: old test solutions and strips can read wrong. Replace the kit once it is past that date.
