Sera Nitrite Test Kit

Makes it easy to monitor the nitrite level in fresh and marine water

Nitrite (NO₂) is among the most toxic substances for fish in aquariums. It can enrich in the water in case of insufficient biological filtration.

The sera NO₂-Test allows monitoring the nitrite level in fresh and marine water easily and reliably.

Sufficient for approx. 75 measurements.

Nitrite is formed as an intermediate product during the breakdown of fish waste. Too high nitrite levels endanger the fish. Nitrite is formed from ammonium and is converted into nitrate by bacteria in a functioning filter or one that has been activated with sera bio nitrivec. Therefore also ammonium and nitrate should be checked regularly, using the sera ammonium/ ammonia-Test kit and the sera nitrate-Test kit. We recommend using sera aquatan and sera bio nitrivec in freshwater aquariums, sera aquatan and sera marin bio reefclear in marine water aquariums, and sera KOI PROTECT and sera pond bio nitrivec in ponds, with every water change.

Directions for use:

Shake reagent bottles well before using! Do not allow tested water to contact aquarium or pond water

1. Rinse the measurement vial several times with the water to be tested, then fill to the 5 ml mark. Dry the vial on the outside.

2. Add 5 drops of reagent 1 into the vial and shake the vial until the liquid is evenly distributed.

3. Add 5 drops of reagent 2 into the vial and shake the same manner.

4. Compare the colors after 5 minutes: Place the vial on the color chart and compare the colors from a position above under natural daylight. Avoid direct sunlight.

5. Cleaning: Clean the vial thoroughly with tap water before and after each test.

Close reagent bottles immediately after use and do not exchange caps. Store at room temperature and away from light.

For testing ornamental fish aquariums and pond water only
