The liquid reagent kit most koi keepers end up owning. Five tests in one waterproof box: pH, high range pH, ammonia (NH3), nitrite (NO2) and nitrate (NO3) — the full nitrogen cycle plus both pH ranges, which matters because established koi ponds often sit above the standard scale. Over 800 tests, with glass test tubes, riveted color cards and a color wallchart.
Liquid reagents take a few minutes longer than strips and are considerably more accurate, which is what you want when a reading is going to decide whether you dose the whole pond.
One gap worth knowing before you buy: this kit does not test carbonate hardness (KH). KH is what anchors pH in a koi pond, and koi ponds consume it continuously — when it runs out, pH stops being held steady and swings hard overnight. Everything else you need is in this box; for KH, pair it with the API GH & KH Test Kit.
