These reagents follow the Zincon Method in which the reaction causes a blue tint in the sample. By simply adding 1 mL of the first reagent to the sample, followed by a packet of the second reagent in the HI758-26 set, the reaction will take place and the HI758 will determine the concentration from the color that is produced. The results will be displayed in ppm of calcium. These reagents are designed to be used with samples that have an expected range of 200 to 600 ppm calcium.\u003c\/p\u003e","brand":"HANNA","offers":[{"title":"Default Title","offer_id":44044192514136,"sku":"14105","price":54.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0712\/8557\/1672\/files\/hi758-26-jpg.webp?v=1779082914"},{"product_id":"hanna-hi713-25-reagents-phosphate-low-range-checker","title":"Hanna - Phosphate LR Reagent","description":"","brand":"HANNA","offers":[{"title":"Default Title","offer_id":44044233539672,"sku":"6456489566","price":17.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0712\/8557\/1672\/files\/HI713-25.jpg?v=1779081750"},{"product_id":"hannamarinephosphate-ultralowrangechecker","title":"Hanna - Phosphorus ULR Checker","description":"\u003cp\u003e \u003c\/p\u003e\n\u003cdiv class=\"product-essential\" style=\"box-sizing: border-box; margin: 0px; padding: 0px; color: #636363; font-family: SohoGothicPro-Light, 'Helvetica Neue', Verdana, Arial, sans-serif; font-size: 14px;\"\u003e\u003cform action=\"https:\/\/hannainst.com.au\/checkout\/cart\/add\/uenc\/aHR0cHM6Ly9oYW5uYWluc3QuY29tLmF1L2hpNzM2LXBob3NwaG9ydXMtdWxyLmh0bWw,\/product\/262\/form_key\/uhWFu2dWQzrQnHmu\/\" method=\"post\" id=\"product_addtocart_form\" style=\"box-sizing: border-box; margin: 0px; padding: 0px;\"\u003e\n\u003cdiv class=\"product-shop\" style=\"box-sizing: border-box; margin: -37px 0px 10px; padding: 0px 0px 0px 15px; width: 615px; float: right;\"\u003e\n\u003cdiv class=\"short-description\" style=\"box-sizing: border-box; margin: 0px 0px 10px; padding: 0px; clear: both;\"\u003e\n\u003cdiv class=\"std\" itemprop=\"description\" style=\"box-sizing: border-box; margin: 0px; padding: 0px;\"\u003e\n\u003cp style=\"box-sizing: border-box; margin: 0px 0px 1.5em; padding: 0px;\"\u003eThe Hanna Phosphorus Ultra Low Range (0 to 200 ppb) Checker\u003cspan style=\"box-sizing: border-box; margin: 0px; padding: 0px; font-size: 10.5px; line-height: 0; position: relative; vertical-align: baseline; top: -0.5em;\"\u003e®\u003c\/span\u003e bridges the gap between simple chemical test kits and professional instrumentation.

Testing for phosphates is standard practice for saltwater aquariums and provides valuable insight into your reef tank’s water chemistry to help ensure long-term coral health. Phosphates are one of the many forms of phosphorus compounds found in marine waters. Excessive phosphate levels can prevent calcification, skeletal formation, and growth of many coral species, particularly those referred to as SPS or small-polyp stony. In addition, high phosphate levels can cause nuisance algae growth in your reef tank. This can become problematic because algae often outcompete sessile organisms for light, nutrients, and space, jeopardizing long term coral health in your reef.\u003c\/p\u003e\n\u003cp style=\"box-sizing: border-box;

Phosphate is a common food additive that enhances flavor and acts as a buffering agent. Important for growth and development of plant roots, phosphate is also present in fertilizers. However, high concentrations of phosphates are detrimental to the environment; for this reason, it is closely monitored in natural and municipal waters.
