In a healthy, fully cycled aquarium, nitrite should then be converted into nitrate. If nitrite builds up, it can quickly become dangerous to fish and invertebrates.\u003c\/p\u003e\n\u003cp\u003eRegular nitrite testing helps you know whether your biological filtration is working properly and whether your aquarium is safe for livestock.\u003c\/p\u003e\n\u003ch3\u003eProduct Details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e API\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct:\u003c\/strong\u003e Nitrite Test Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTests:\u003c\/strong\u003e Up to 180 tests\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse:\u003c\/strong\u003e Freshwater and saltwater aquariums\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasures:\u003c\/strong\u003e Nitrite\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eWhy is testing nitrite important?\u003c\/h4\u003e\n\u003cp\u003eNitrite is toxic to fish and invertebrates, even at low levels. Testing helps you catch unsafe nitrite levels early, especially during the cycling process or after a filter issue.\u003c\/p\u003e\n\u003ch4\u003eWhat is a safe nitrite level?\u003c\/h4\u003e\n\u003cp\u003e0 ppm is ideal. Any detectable nitrite should be addressed quickly because nitrite can harm fish and other aquarium livestock.\u003c\/p\u003e\n\u003ch4\u003eCan I use the API Nitrite Test Kit in freshwater and saltwater aquariums?\u003c\/h4\u003e\n\u003cp\u003eYes.

In established aquariums, test weekly or anytime fish appear stressed, after adding new fish, after overfeeding, or if your filter has stopped working.\u003c\/p\u003e\n\u003ch4\u003eWhat causes nitrite spikes?\u003c\/h4\u003e\n\u003cp\u003eNitrite spikes can happen in new aquariums, after overfeeding, after a fish loss, from an uncycled or damaged filter, or when too many fish are added too quickly.\u003c\/p\u003e\n\u003ch4\u003eHow do I lower nitrite in an aquarium?\u003c\/h4\u003e\n\u003cp\u003eIf nitrite is present, perform a water change, avoid overfeeding, make sure the filter is running properly, and continue testing. Beneficial bacteria products may also help support the biological filter.\u003c\/p\u003e\n\u003ch3\u003eKeep Your Aquarium Water Safe\u003c\/h3\u003e\n\u003cp\u003eThe API Nitrite Test Kit is a must-have tool for aquarium owners.
