Providing approximately 600 phosphate measurements per kit, these reagents allow reef aquarium owners to follow changing phosphate concentrations, assess nutrient export performance, and maintain better control over one of the most important nutrients affecting coral health and algae growth.\u003c\/p\u003e\n\u003ch3\u003eMonitor Phosphate Trends with Automated Testing\u003c\/h3\u003e\n\u003cp\u003ePhosphate (PO4) is an essential nutrient in marine aquariums, but excessive accumulation or aggressive nutrient removal can create problems for sensitive corals. Phosphate levels may change with feeding, filtration, water changes, and the use of phosphate-removing media. Regular measurements help identify these changes before they become larger water quality concerns.\u003c\/p\u003e\n\u003cp\u003eThe Mastertronic Essential combines the Focustronic reagents with automated colourimetric analysis to provide repeatable phosphate measurements and recorded results without the need to manually perform every test.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eApproximately 600 tests:\u003c\/strong\u003e High testing capacity for routine phosphate monitoring.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo-part chemical system:\u003c\/strong\u003e Formulated for the Mastertronic Essential automated phosphate testing procedure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull-range monitoring:\u003c\/strong\u003e Focustronic phosphate reagents support measurements across approximately 0 to 2.0 mg\/L.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer-specified accuracy:\u003c\/strong\u003e Approximately ±0.01 mg\/L when using the supported testing method.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUseful for nutrient management:\u003c\/strong\u003e Helps evaluate feeding practices, phosphate absorbers, refugiums, and other nutrient export methods.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eChoosing the Appropriate Phosphate Testing Range\u003c\/h3\u003e\n\u003cp\u003eFocustronic recommends its phosphate reagent for general monitoring, particularly when phosphate is approximately 0.10 mg\/L or higher. For mature, low-nutrient reef aquariums where distinguishing very small changes below 0.10 mg\/L is especially important, the manufacturer recommends the compatible Red Sea Pro phosphate reagent profile for higher sensitivity in that range. This Focustronic kit is intended for Mastertronic Essential and is not currently approved for the original Mastertronic.\u003c\/p\u003e\n\u003ch3\u003eDirections\u003c\/h3\u003e\n\u003cp\u003eInstall the reagents in the designated Mastertronic Essential phosphate vial positions 9 and 10, following the manufacturer's instructions. Select the Focustronic phosphate reagent profile in the app and update the reagent volumes after filling. If changing from another reagent brand, perform the prescribed vial and reagent line rinsing procedure to prevent cross-contamination. Configure the preferred testing schedule and review phosphate trends alongside nitrate readings for a more complete understanding of aquarium nutrient conditions.\u003c\/p\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePhosphate Reagent 1 - 150 ml (5.07 US fl oz)\u003c\/li\u003e\n\u003cli\u003ePhosphate Reagent 2 - 50 ml (1.69 US fl oz)\u003c\/li\u003e\n\u003cli\u003eEnough reagents for approximately 600 automated phosphate tests\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Focustronic","offers":[{"title":"Default Title","offer_id":67647238275162,"sku":"FT-RPO4","price":72.95,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/1636\/7450\/files\/phosphate-reagent-kit.png?v=1791927360","url":"https:\/\/jlaquatics.com\/products\/focustronic-phosphate-reagent-kit","provider":"J\u0026L Aquatics Ltd.","version":"1.0","type":"link"}
