Three Top Ammonia Test Kits for Happy Fish

Ammonia test kits are an essential item for all fish keepers. Ammonia is a key parameter to monitor as it is acutely toxic but continuously being produced by the fish. These drop kits are much more reliable than test strips and very simple to use. They are not accurate enough to use at different sample points around a system but their ease of use and low cost means they are an excellent choice to ensure that safe levels are maintained.

All these test kits test for Total Ammonia Nitrogen (TAN) and consequently may NOT indicate actual toxic levels. For this you need to record water temperature and pH and use a Table that shows the percentage present of the toxic NH3 proportion of the TAN.

Further Information

Why you need to test for ammonia

Ammonia is continually being excreted by all aquatic animals. If it is not broken down, or removed, it can quickly kill your fish. At the very least they become more stressed and more susceptible to disease. Visual signs of ammonia toxicity include;

  • swimming close to water surface or inlet
  • reddening of the skin
  • loss of appetite

Unfortunately this signs can equally apply to a range of other water quality and disease situations. They cannot be relied upon as a diagnosis. Ammonia may be suspected but needs to be confirmed with a test kit.
