Help make your aquarium a safe, healthy place for your finned friends with API Ammonia Freshwater & Saltwater Test Kit. With this bundle, it's easier than ever to test your tank for harmful ammonia. Tropical fish continually release ammonia through their gills, urine and solid waste, but it also accumulates through uneaten fish food. This kit comes with everything you need to test your water, so you can take quick action if your ammonia levels are raised. Using a color coding system that is easy to read, simply combine a few drops of the aquarium water in the included test tube with the solution, and review your results.

Key Benefits
  • Ammonia liquid testing kit accurately tests the ammonia level in freshwater and saltwater tanks.
  • Uses an easy-to-read color chart and clear instructions to determine if your levels are too high.
  • Tests ammonia levels from 0 to 8 ppm and includes 130 tests for regular testing.
  • Simply combine drops of aquarium water and the tester solution in the included glass tube.
  • Ammonia is the number one killer of tropical fish, so testing is an essential part of your routine.

Help protect your fish and neutralize ammonia with API's Ammo-Lock Detoxifier.

This kit contains: 2 liquid dropper bottles with child-resistant safety caps, easy-to-read instructions with information on how to test and how to correct unsafe water conditions, 2 color charts and glass test tube with snap-tight cap.


Is it correct for the #2 bottle in the API AMMONIA TEST KIT to have a slightly bigger hole in the spout than the #1 does? I’m concerned my test kit isn’t accurate because of this.

The dropper tips are all the same, but the viscosity of the liquids are different. Drops may appear to be larger coming out due to the thickness of the drop.

    Thanks for the quick help

    By Finigan on Apr 11, 2021

    First of all this is a terrific company I have used for kitty supplies for a long time. I recently set up an aquarium and had a minor crisis. Without leaving my house I was able to quickly identify and correct the problem. On my porch the next day and solved the problem.

    Simply to use

    By Angel on Jul 1, 2020

    The instructions for use is easy to read and understand and are in multiple different languages. The color chart is eady to understand. The water color that is being tested in the tube, after test solutions added, are clear and sharply obvious colors so easy to match to color chart to determine the levels.

    Liquid tests are key

    By Delilah on Oct 14, 2018

    I’ve been using this product for over 10 years. Dip strips are just NOT the same. The liquid test is more precise, more accurate and easier to read, in my opinion. Also, very important, if you don’t have a bunch of tanks, it’s very important to rebuy before the expiration - you may not go through the whole bottle before then if you have just a single 10 gallon tank.

    This test kit is easy to use and accurate.

    By BobG on Jun 13, 2018

    Ammonia is one of the worst things to have in an aquarium. There is no way of knowing whether your aquarium has it without testing for it-sick or dying fish can be due to other causes. This test will quickly and easily let you know whether your tank does have ammonia.

    By Kristina on Apr 19, 2018

    I'm new to fish keeping but this has made it easy to check my waters.. they have made it easy to see the levels your water is at with a picture on the side of the bottle that you put the strip up to it and see based on the coloring. I use this and I bought the ammonia kit's to make sure my tank is safe for my betta
