ASKOLL TEST NO2 – Nitrite Testing Kit for Aquariums
ASKOLL TEST NO2 is a reliable and easy-to-use test kit designed to accurately detect nitrite (NO2) levels in both freshwater and marine aquariums. Nitrites are highly toxic to fish, impairing their blood’s oxygen-carrying capacity, and must be monitored regularly—especially in newly set-up tanks or in cases of biological imbalance. Excess nitrites can cause stress, appetite loss, disease, and even death in fish.
This kit includes a graduated test vial, a 10 ml reagent bottle, and a color chart for quick and accurate results. The testing process takes just a few minutes and is suitable for both beginners and experienced aquarists seeking to maintain optimal water conditions.
Kit contents:
• 1 graduated test vial
• 1 x 10 ml NO2 reagent bottle
• 1 color comparison chart
• 1 instruction leaflet
Recommended values:
• Freshwater: max 0.1 mg/L
• Marine: max 0.05 mg/L

Instructions for use:

Add 5 drops of NO2 reagent, shake well, and wait 5 minutes.
