Designed to support precise calcium monitoring in marine reef aquariums, this kit provides approximately 200 automated calcium tests, helping aquarists track calcium consumption and maintain an appropriate balance between calcium, alkalinity, and magnesium.\u003c\/p\u003e\n\u003ch3\u003eAccurate Calcium Testing for Coral Growth\u003c\/h3\u003e\n\u003cp\u003eCalcium is a major component of stony coral skeletons and coralline algae, making regular testing important in aquariums with growing calcifying organisms. As coral demand changes, calcium levels can gradually drift from the desired range even when supplementation is maintained. The Mastertronic Essential uses these reagents with its automated colourimetric testing system to measure calcium concentrations and record results through the Focustronic app.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMastertronic Essential compatible:\u003c\/strong\u003e Formulated for the manufacturer's current multi-parameter automated testing system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApproximately 200 tests:\u003c\/strong\u003e Provides an extended supply for scheduled calcium measurements.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree-part reagent kit:\u003c\/strong\u003e Includes the individual solutions required for the supported Focustronic calcium testing procedure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTesting performance:\u003c\/strong\u003e Mastertronic Essential specifies calcium measurement accuracy of approximately ±6 mg\/L when operated according to manufacturer instructions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUseful for supplementation monitoring:\u003c\/strong\u003e Helps identify calcium consumption trends and evaluate the effectiveness of existing dosing schedules.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eReagent Preparation and System Compatibility\u003c\/h3\u003e\n\u003cp\u003eThis reagent kit is intended for the Mastertronic Essential and is not currently approved by Focustronic for the original Mastertronic. Each solution must be placed in its designated internal vial according to the manufacturer's reagent layout. Calcium Reagent 2 must be shaken vigorously for at least 30 seconds before being transferred into the testing vial to ensure proper reagent consistency. The kit is a chemical refill and does not include the automatic testing instrument.\u003c\/p\u003e\n\u003ch3\u003eDirections\u003c\/h3\u003e\n\u003cp\u003eBefore refilling, confirm that the Mastertronic Essential is configured for Focustronic calcium reagents. Shake Calcium Reagent 2 vigorously for a minimum of 30 seconds and gently mix the other reagents as instructed. Transfer the solutions into the designated calcium reagent vials, positions 4, 5, and 11, without exceeding the recommended fill level. Ensure the required stirring component is installed in vial 5, update reagent quantities in the Focustronic app, and follow the manufacturer's testing and maintenance instructions. Avoid mixing different reagent brands or contaminating the testing vials.\u003c\/p\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCalcium Reagent 1 - 50 ml (1.69 US fl oz)\u003c\/li\u003e\n\u003cli\u003eCalcium Reagent 2 - 50 ml (1.69 US fl oz)\u003c\/li\u003e\n\u003cli\u003eCalcium Reagent 3 - 200 ml (6.76 US fl oz)\u003c\/li\u003e\n\u003cli\u003eEnough reagents for approximately 200 automated calcium tests\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Focustronic","offers":[{"title":"Default Title","offer_id":67711769313568,"sku":"FT-RCAL","price":49.95,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0951\/8222\/5696\/files\/calcium-reagent-kit.png?v=1791927432","url":"https:\/\/aquariumsupplydirect.com\/products\/focustronic-calcium-reagent-kit","provider":"J\u0026L Aquatics - Aquarium Supply Direct","version":"1.0","type":"link"}
