Nitrite Test Kits Help and Advice

Quickly determine dangerous nitrite levels

As bacteria break down ammonia, they convert ammonia to Nitrite, a less toxic substance. While it is less toxic than ammonia, over time, high levels of nitrite will disrupt the metabolism of your fish and eventually destroy their oxygen-carrying cells, resulting in suffocation. At Swell UK we provide an excellent range of nitrite test kits from leading brands that allow you to accurately measure nitrite levels.

What are nitrite test kits?

Nitrite is produced by beneficial filtration bacteria as they break down the harmful waste ammonia excreted by the fish. Like ammonia, it's not visible to the naked eye. Although it is not as toxic as ammonia, nitrite is still very damaging to the health of fish. Nitrite test kits read nitrite levels quickly and accurately in your tank, and test parameters from 0 to 5 ppm.

Why might I buy nitrite test kits?

To keep your saltwater reef aquarium healthy, you want to maintain low nitrites (under 150 ppb) to ensure the health of fish and corals. It's important to test for nitrite when an aquarium is first being set up and when the tank is being cycled to make sure waste is being properly recycled.

What accessories should I buy with nitrite test kits?

If any nitrite is detected in your aquarium, determine the cause for the elevated nitrite (e.g. changes in stocking density, overfeeding, filter maintenance etc). Monitor livestock for changes and ill-health and carry out partial water changes to dilute nitrite if necessary. Add NT Labs Marine Live Filter Bacteria to help repopulate the filter with marine nitrifying bacteria and restart the biological filtration.
