Testing Equipment

Accurate testing is the foundation of a stable reef. From daily alkalinity checks to full parameter panels, this range covers the test kits, reagents, and digital checkers reef keepers rely on to know exactly what's happening in their tank, not guess at it.

Whether you're running a quick Salifert check or relying on a Hanna Checker for repeatable precision, testing regularly is what catches small shifts before they become real problems.

Includes test kits, reagents, digital checkers, and refill supplies for alkalinity, calcium, magnesium, nitrate, phosphate and more.
