Utilizing a simple drop-by-drop color-change method, each drop of reagent added to the water sample corresponds directly to one German degree (°dGH or °dKH), providing clear, instant results without complex color matching charts. Monitoring general hardness ensures proper mineral levels (calcium and magnesium) for optimal fish osmoregulation and plant growth, while tracking carbonate hardness is essential for maintaining buffer capacity to prevent sudden, dangerous pH crashes.\u003c\/p\u003e","brand":"Williamstown Aquarium","offers":[{"title":"Default Title","offer_id":56582866305329,"sku":null,"price":29.95,"currency_code":"AUD","in_stock":true}],"url":"https:\/\/www.williamstownaquarium.com.au\/products\/tropical-aqua-care-gh-kh-test-kit","provider":"Williamstown Aquarium","version":"1.0","type":"link"}
