Benchmark Alkalinity Test Kit begins with one simple rule: test first, then dose.
It is a practical saltwater aquarium kit built around routine alkalinity readings, Reagent A, and Reagent B. The aim is simple: make the number easy to keep in view before the next decision.
A measured routine
Good reefkeeping is built from repeated observations. A clear reading gives you a useful place to start, whether you are checking a familiar system or investigating a change.
Part of Benchmark
The Alkalinity Test Kit sits alongside the Benchmark Chemistry Portal, Calcium & Magnesium testing, and ICP-OES water testing. Each surface follows the same idea: keep the reading clear, then decide what comes next.
