JBL TEST NO3 – Nitrate Test Kit for Aquariums and Ponds with Optical Color Compensation
JBL Test NO3 is a professional-grade test for fast and accurate measurement of nitrate (NO3⁻) levels in freshwater, saltwater aquariums, and garden ponds. Nitrates, the final stage of the nitrogen cycle, accumulate over time and may lead to algae growth and reduced water quality if not properly managed.
This JBL kit provides up to 50 tests using high-quality glass cuvettes and a precise 11-color comparison scale ranging from light yellow to red-orange. It covers a wide testing range of 0 to 240 mg/l, allowing detailed assessment in both low-nutrient and high-load systems.
The built-in color compensation system ensures high accuracy by accounting for water discoloration, and the included syringe makes water sampling easy and precise. Regular nitrate monitoring is essential to manage nutrient balance and maintain a clean, healthy aquatic environment—especially in planted tanks or reef systems.
