API Nitrite Test Kit – Accurate Aquarium Water Testing
Product Overview
The API Nitrite Test Kit is designed to accurately measure nitrite levels in your aquarium, ensuring a safe environment for your fish. Nitrite is a toxic compound produced from fish waste, uneaten food, and nitrifying bacteria during the natural nitrogen cycle. Even low nitrite levels can inhibit respiration and weaken fish immunity, while high levels can be deadly.
This test kit provides quick, accurate readings from 0 to 5 ppm for both freshwater and saltwater aquariums, helping you maintain healthy water quality for your aquatic life.
