NO2 test

This nitrite test kit is intended for aquarium setups where the nitrogen cycle is not closing properly. Because high nitrite concentrations are harmful to aquatic animals, regular measurement is the only way to confirm that the water is safe and that the cycle is progressing.

Why it matters

• Targets nitrite (NO2) specifically, the compound that signals an incomplete nitrogen cycle.
• Recommended for tanks where the nitrogen cycle has been difficult to close, so readings can be taken during that period.
• Comes with a colour scale, which allows the result to be read by comparing the test colour against reference shades.
• Contains all components needed for a measurement in one set: test tube, reagents, syringe, measuring scoop and instructions.

What it works with

The kit belongs to the water chemistry and testing category for exotic aquatic setups. It is used alongside the aquarium itself: the syringe and test tube take a water sample, the reagents react with nitrite, and the colour chart gives the reading. Tank volume is not specified in the product data.
