Containing five individual reagent kits for calcium, magnesium, phosphate, nitrate, and alkalinity, this comprehensive set allows reef aquarium owners to establish or replenish all five major chemical testing functions using Focustronic's dedicated reagent formulations. It is an ideal starting point for a newly installed Mastertronic Essential or a convenient way to restock multiple testing parameters together.\u003c\/p\u003e\n\u003ch3\u003eComplete Five-Parameter Automated Reef Water Testing\u003c\/h3\u003e\n\u003cp\u003eSuccessful reef aquarium maintenance depends on understanding both the major elements consumed during coral growth and the nutrients affected by feeding, filtration, and biological activity.

The full set does not include the automated testing instrument or an Alkatronic reagent supply. Mastertronic Essential supports one scheduled alkalinity test per day, and its alkalinity readings cannot directly control Dosetronic dosing. A separate Alkatronic system is required for frequent automatic alkalinity measurements and active dKH correction.\u003c\/p\u003e\n\u003ch3\u003eDirections\u003c\/h3\u003e\n\u003cp\u003eInstall the reagents in the Mastertronic Essential according to Focustronic's specified vial arrangement: magnesium in positions 1-3, calcium in positions 4, 5, and 11, alkalinity in positions 6 and 12, nitrate in positions 7-8, and phosphate in positions 9-10. Shake Nitrate Reagent 2 vigorously for at least 90 seconds and Calcium Reagent 2 for at least 30 seconds before filling their designated vials. Confirm the correct stirring components are installed, select the appropriate Focustronic reagent profiles in the app, and record the filled reagent volumes. Configure individual testing schedules, monitor remaining solution quantities, and follow the manufacturer's maintenance procedures. Avoid mixing reagent types or switching brands without the recommended rinsing process.\u003c\/p\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOne Focustronic Calcium Reagent Kit - approximately 200 tests\u003c\/li\u003e\n\u003cli\u003eOne Focustronic Magnesium Reagent Kit - approximately 83 tests\u003c\/li\u003e\n\u003cli\u003eOne Focustronic Phosphate Reagent Kit - approximately 600 tests\u003c\/li\u003e\n\u003cli\u003eOne Focustronic Nitrate Reagent Kit - approximately 200 tests\u003c\/li\u003e\n\u003cli\u003eOne Focustronic Alkalinity Reagent Kit - approximately 133 tests\u003c\/li\u003e\n\u003cli\u003e12 individual reagent bottles in total\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Focustronic","offers":[{"title":"Default Title","offer_id":67711768854816,"sku":"FT-RZFULL","price":249.95,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0951\/8222\/5696\/files\/focustronic-reagent-full-set.png?v=1792008419","url":"https:\/\/aquariumsupplydirect.com\/products\/focustronic-reagent-full-set-ca-mg-po4-no3-kh","provider":"J\u0026L Aquatics - Aquarium Supply Direct","version":"1.0","type":"link"}
