For freshwater, aquatic plant, saltwater, reef aquariums and ponds

NO2 is transformed from NH3 /NH4, and is the side product when bacteria

decompose protein.  Even when NO2 level is only slightly above 0.1 mg/l,

it will poison fishes.  NO2 usually causes the symptoms in fish such as,

bad appetite, fading body colors, insufficient oxygen uptaking,

vulnerable to fish diseases.  So, NO2 level is a very important factor in water.

NO2 level should be maintained at 0 mg/l in aquariums.

Each kit includes a sample vial, and reagent for 35 tests.

ANALYSIS:

1. When NO2 level is above 0.1 mg/l, it will be harmful for fish.

    So, NO2 had better be maintained at 0 mg/l.

2. When NO2 is found in the aquarium, please have a water change and add

    AZOO BIO-BACTERIA immediately.

RANGE:
