Salifert Nitrite Test Kit 50T – Ultra-Low NO₂ Testing for Aquariums

Nitrite (NO₂) is a highly toxic compound that can quickly endanger fish and invertebrates if left unchecked. The Salifert Nitrite Test Kit 50T is designed to accurately measure nitrite levels in both freshwater and saltwater aquariums, making it an essential tool during tank cycling and routine water quality monitoring.

This professional-grade test kit features two precision testing ranges. The ultra-low scale allows detection of trace nitrite-nitrogen levels critical for reef and marine systems, while the medium scale is ideal for freshwater and higher bioload aquariums. Clear, sharp color changes ensure results are easy to read and interpret with confidence.
