These pre-measured reagents are formulated with high-purity chemicals to deliver fast, accurate, and repeatable nitrate readings using Hanna’s digital colorimeter system. By eliminating guesswork and subjective color matching, they allow reef hobbyists to confidently monitor nitrate levels—one of the most critical parameters for controlling algae and maintaining coral health.

Each pack provides approximately 25 tests and uses a colorimetric reaction to measure nitrate concentrations in saltwater aquariums. The reagents are individually sealed and labeled with lot numbers and expiration dates for traceability and reliability.

Whether you're managing nutrient levels in an SPS-dominant reef or maintaining stability in a mixed system, these reagents are essential for consistent, data-driven reef care.
