Refill for the ZOOLEK AQUASET NO2 test kit (model ZO TEST NO2 UZUP). Contains replacement reagents and materials required to continue measuring nitrite (NO2) levels in aquarium or pond water using the original AQUASET test system.

## Long description

Refill for the ZOOLEK AQUASET NO2 test kit provides the reagents and consumable materials needed to continue measuring nitrite (NO2) concentration in aquarium and pond water with the ZOOLEK AQUASET system. The refill is designed to be used with the original test kit components, enabling routine monitoring of water quality and early detection of elevated nitrite levels that can affect fish health.
Advantages
The refill contains calibrated reagents formulated for the AQUASET NO2 chemistry, ensuring consistent test reactions when used according to the kit instructions. Using a dedicated refill reduces waste by replacing only depleted components rather than the entire kit. The refill supports repeated measurements over multiple testing cycles and maintains compatibility with the original test vials, color charts, and measuring tools supplied with the AQUASET NO2 kit.
Suitable for
 Routine aquarium water testing to track nitrite levels
 Pond water monitoring where nitrite control is required
 Regular maintenance checks after filter changes, stocking, or medication
 Hobbyists and professionals performing frequent water quality assessments
Key specifications
 Contents: replacement reagents and consumables compatible with the AQUASET NO2 test methodology
 Target analyte: nitrite (NO2) in freshwater and pond water
 Intended use: multiple test cycles for routine monitoring
 Compatibility: designed for use with original AQUASET NO2 test vials and measuring accessories

How to use
Replace the depleted reagents and consumables in your existing AQUASET NO2 test kit following the sequence and volumes indicated in the original kit instructions. Collect a water sample from the aquarium or pond in the supplied test vial, add the specified reagent drops or measured reagent amounts from the refill, mix gently, and wait the recommended reaction time. Compare the resulting color against the kit’s reference chart or follow any photometric reading procedure if applicable. Record the measured nitrite concentration and repeat testing at intervals appropriate for your system.
Usage recommendations
Use the refill only with the original ZOOLEK AQUASET NO2 test kit to ensure accurate results. Dispose of used reagent containers according to local regulations. If test results indicate elevated nitrite, take corrective measures such as partial water changes, review filtration and biological load, and retest frequently until levels are within the safe range for your fish and plants.
