How to read it
Two dropper bottles go into a sample in the test tube; compare the color with the chart. The instructions say how to correct a high reading.

Before choosing this model

  • Ammonia is the first reading to watch in a new tank: test several times a week for the first 4 to 6 weeks, as API advises.

What API doesn’t publish

  • API doesn’t print how many tests the bottles hold.

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

  • 2 liquid dropper bottles
  • instructions
  • 2 color charts
  • test tube with snap-tight cap

Plan for the routine work

  • After the first weeks, test weekly or whenever something looks wrong.
  • Rinse the test tube with water right after each test, as API advises, so the reagent doesn’t stain it.

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.
