Like ammonia, it is not visible to the naked eye. Although it is not as toxic as ammonia, nitrite is still very damaging to the health of the fish. Nitrite itself is broken down into nitrate, which is practically harmless to fish.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the correct nitrite level?\u003c\/strong\u003e\u003cbr\u003eThere is no occasion where any nitrite is tolerable in an aquarium. A level of zero mg\/L (ppm) should be maintained at all times.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat do I do if the Nitrite level is wrong?\u003c\/strong\u003e\u003cbr\u003eIf 0.25 – 0.5 mg\/l (ppm) of nitrite is found, then add \u003ca href=\"https:\/\/www.ntlabs.co.uk\/browse-products\/outdoor\/koi-care\/filter-bugs\/\"\u003eFilter Bugs\u003c\/a\u003e. If a level above this is recorded, then a substantial water change is essential. Change 25% of the water volume for 1 mg\/l (ppm) nitrite and 50% for nitrite levels above this. If any level of nitrite is detected \u003ca href=\"https:\/\/www.ntlabs.co.uk\/browse-products\/outdoor\/koi-care\/zeolite\/\"\u003eZeolite\u003c\/a\u003e will remove ammonia (and thus nitrite) from the water and can be recharged. If you do record a nitrite level, then it is important to check other vital water quality parameters, especially pH and ammonia.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow to use?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eEnsure the test tube is clean.\u003c\/li\u003e\n\u003cli\u003eTake a 5 ml sample of water into the test tube.\u003c\/li\u003e\n\u003cli\u003eAdd 5 drops of the Nitrite reagent.\u003c\/li\u003e\n\u003cli\u003eReplace the test tube cap and shake thoroughly.\u003c\/li\u003e\n\u003cli\u003eWait 2 minutes, then compare the colour of the sample to the colour scale provided.
