Designed to measure calcium, magnesium, nitrate, phosphate, alkalinity, and Focustronic's Organic Level Index, the Mastertronic Essential automates many of the repetitive testing tasks normally performed with individual liquid test kits. Its integrated reagent storage, colour-based measuring technology, programmable testing schedules, and compatibility with other Focustronic equipment make it an advanced solution for aquarists seeking detailed water chemistry records and more consistent reef maintenance.\u003c\/p\u003e\n\u003ch3\u003eSix Water Quality Measurements in One Automated System\u003c\/h3\u003e\n\u003cp\u003eMaintaining a thriving reef aquarium involves more than checking alkalinity alone. Calcium and magnesium must remain balanced with coral consumption, while nitrate and phosphate require monitoring to avoid undesirable nutrient conditions. The Mastertronic Essential brings these measurements together in one programmable testing platform.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCalcium (Ca):\u003c\/strong\u003e Tracks an essential component of coral skeletal growth and helps identify changing supplementation requirements.
