These reagents follow the colorimetric EDTA method using calmagite\nindicator in which the reaction between magnesium and the reagent causes a\nblue to violet tint in the sample. By simply adding the packet of HI783-25\nreagent to the sample, the reaction will take place and the HI783 will\ndetermine the concentration from the color that is produced. The results will\nbe displayed in ppm of Magnesium. These reagents are designed to be used with\nsaltwater samples that have an expected range of 1,000 to 1,800 ppm.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n \u003cul class=\"a\"\u003e\n \u003cli\u003ePre-made reagents for ease of use\u003c\/li\u003e\n \u003cli\u003ePrepared with high purity chemicals\u003c\/li\u003e\n \u003cli\u003eMarked with expiration date and lot number for traceability\u003c\/li\u003e\n \u003c\/ul\u003e","published_at":"2026-11-12T23:14:58+11:00","created_at":"2026-11-12T20:38:09+11:00","vendor":"Hanna Instruments","type":"Aquarium Test Kits","tags":["pets_selected_Nov2026"],"price":21600,"price_min":21600,"price_max":21600,"available":true,"price_varies":false,"compare_at_price":null,"compare_at_price_min":0,"compare_at_price_max":0,"compare_at_price_varies":false,"variants":[{"id":45254820954312,"title":"Default Title","option1":"Default Title","option2":null,"option3":null,"sku":"B0B33C2FBW","requires_shipping":true,"taxable":true,"featured_image":null,"available":true,"name":"Hanna Marine Magnesium Checker® Reagents (25 Tests) HI783-25","public_title":null,"options":["Default Title"],"price":21600,"weight":272,"compare_at_price":null,"inventory_management":"shopify","barcode":null,"requires_selling_plan":false,"selling_plan_allocations":[],"quantity_rule":{"min":1,"max":null,"increment":1}}],"images":["\/\/pawsplanetshop.com\/cdn\/shop\/files\/B0B33C2FBW.jpg?v=1794476291"],"featured_image":"\/\/pawsplanetshop.com\/cdn\/shop\/files\/B0B33C2FBW.jpg?v=1794476291","options":["Title"],"media":[{"alt":null,"id":31381319909576,"position":1,"preview_image":{"aspect_ratio":0.623,"height":1500,"width":934,"src":"\/\/pawsplanetshop.com\/cdn\/shop\/files\/B0B33C2FBW.jpg?v=1794476291"},"aspect_ratio":0.623,"height":1500,"media_type":"image","src":"\/\/pawsplanetshop.com\/cdn\/shop\/files\/B0B33C2FBW.jpg?v=1794476291","width":934}],"requires_selling_plan":false,"selling_plan_groups":[],"content":"\u003ch3\u003eHanna Marine Magnesium Checker® Reagents (25 Tests) HI783-25\u003c\/h3\u003e\n\u003cp id=\"b\"\u003eThe HI783-25 are the replacement reagents for the Marine Magnesium Checker HC\n- HI783.
