GH (general hardness) measures dissolved minerals, mostly calcium and magnesium, which shrimp use to build a new shell after moulting, the shedding of the old shell as they grow. KH (carbonate hardness) measures the water's buffering capacity, meaning its resistance to sudden pH swings.\u003c\/p\u003e\n\u003ch2\u003eKey Benefits\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eReads GH and KH separately, which a TDS meter cannot do\u003c\/li\u003e\n\u003cli\u003eDrop-count method needs no colour chart to interpret\u003c\/li\u003e\n\u003cli\u003eShows whether tap water or remineralised water is where you want it\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eUsage \u0026amp; Instructions\u003c\/h2\u003e\n\u003cp\u003eShake each bottle, fill the tube to the marked line reading from the bottom of the curve in the water surface, then add drops one at a time while counting, swirling between drops, until the colour change described on the instructions holds. Hold the bottle fully upside down so drop size stays consistent. Rinse the tube afterwards.\u003c\/p\u003e\n\u003ch2\u003eRisk \u0026amp; Awareness\u003c\/h2\u003e\n\u003cp\u003eReagents start to degrade once opened and have a use-by date, so replace old bottles rather than trust a doubtful reading. Do not tip tested water back into the tank. Keep reagents out of reach of children, away from heat and sunlight, and never swap caps between bottles.\u003c\/p\u003e","brand":"Shrimp Zone","offers":[{"title":"Default Title","offer_id":52845949911352,"sku":"PLACEHOLDER-gh-and-kh-test-kit","price":29.0,"currency_code":"AUD","in_stock":true}],"url":"https:\/\/shrimpzone.com.au\/products\/gh-and-kh-test-kit","provider":"Shrimp Zone ","version":"1.0","type":"link"}
