Collection: API

API is the brand most aquarists learn to test their water with. This collection covers the full API testing range for freshwater, saltwater and reef systems — the Master kits plus single-parameter tests for ammonia, nitrite, nitrate, pH, phosphate, calcium and alkalinity.

It also carries API's everyday water care: Stress Coat and Stress-Zyme for conditioning and biological support, and Leaf Zone for planted tanks. Reagent kits stay accurate longer than strips as long as they are in date. Ships across Canada.
