Uneaten food and other decaying organic matter also add ammonia to the water. A natural mechanism exists that controls ammonia in the aquarium – the biological filter. It is made up of nitrifying bacteria, which live in the gravel bed. However, as with any natural process, imbalances can occur. Testing for the presence of toxic ammonia is essential, so that once detected, steps can be taken to remove it. Otherwise, ammonia in the aquarium will damage gill membranes, and prevent fish from carrying on normal respiration. High levels of ammonia quickly lead to fish death. Even trace amounts stress fish, suppressing their immune system and thereby increasing the likelihood of disease outbreaks and subsequent fish loss.\u003c\/p\u003e\n\u003cp\u003e \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eTesting Tips:\u003c\/strong\u003e\u003cbr\u003eThis salicylate based ammonia test kit reads the total ammonia level in parts per million (ppm) which are equivalent to milligrams per Liter (mg\/L) from 0 ppm to 8.0 ppm (mg\/L), in either fresh or saltwater aquariums.

This kit includes two Nitrate Test Color Charts — one for freshwater aquariums, and one for saltwater aquariums — so be sure to use the correct chart for your type of aquarium when interpreting test results. The Freshwater Nitrate Test Color Chart is the appropriate chart to use for testing freshwater aquariums to which salt has been added. This test kit measures nitrate as nitrate ion or “total nitrate.” Other nitrate test kits that measure “nitrate-nitrogen” (NO3-N) will give readings 4.4 times LESS than this test kit.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFAQs\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv class=\"Accordion-panel\" aria-labelledby=\"accordion6id\" role=\"region\" id=\"sect8\"\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eAre high nitrate levels harmful to fish?\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eHigh nitrate is harmful to fish, but is significantly less toxic than ammonia or nitrite.

A pH reading of 7.0 is neutral. A pH higher than 7.0 is alkaline, and a pH lower than 7.0 is acidic. Certain freshwater fish thrive at a pH above 7.0. Live-bearers and goldfish require a pH of 7.5. African cichlids, marine fish and invertebrates require a pH between 8.2 and 8.4. Maintaining the aquarium at the proper pH ensures optimal water quality.\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cmeta charset=\"utf-8\"\u003e\n\u003cstrong\u003eWhy Test For Nitrite?\u003c\/strong\u003e\u003cbr\u003eNitrite (NO2-) is produced in the aquarium by the biological filter. Beneficial bacteria in the biological filter convert toxic ammonia into nitrite (also toxic). The biological filter then converts nitrite into nitrate (NO3-). Testing for the presence of toxic nitrite is essential, so that once detected, steps can be taken to remove it. Otherwise, nitrite in the aquarium will prevent fish from carrying on normal respiration. High levels of nitrite quickly lead to fish death. Even trace amounts of nitrite stress fish, suppressing their immune system and, thereby, increase the likelihood of disease and subsequent fish loss.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cstrong\u003eWhy test for Ammonia?\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eTropical fish continually release ammonia (NH3) directly into the aquarium through their gills, urine, and solid waste. Uneaten food and other decaying organic matter also add ammonia to the water. A natural mechanism exists that controls ammonia in the aquarium – the biological filter. It is made up of nitrifying bacteria, which live in the gravel bed. However, as with any natural process, imbalances can occur. Testing for the presence of toxic ammonia is essential, so that once detected, steps can be taken to remove it. Otherwise, ammonia in the aquarium will damage gill membranes, and prevent fish from carrying on normal respiration. High levels of ammonia quickly lead to fish death. Even trace amounts stress fish, suppressing their immune system and thereby increasing the likelihood of disease outbreaks and subsequent fish loss.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cmeta charset=\"utf-8\"\u003e\n\u003cstrong\u003eWhy Test For Nitrate?\u003c\/strong\u003e\u003cbr\u003eNitrate (NO3-) is produced in the aquarium by the biological filter. Beneficial bacteria in the biological filter convert toxic ammonia and nitrite into nitrate. A high nitrate level indicates a build-up of fish waste and organic compounds, resulting in poor water quality and contributing to the likelihood of fish disease. Excessive nitrate also provides a nitrogen source that can stimulate algal blooms.
