Different fish species require different hardness levels, so regular testing helps you create water conditions that closely match their natural habitat.\u003c\/p\u003e\n\u003cp\u003eThe test uses a simple drop-count method. Add the reagent drop by drop until the sample changes from red through brown to green. The number of drops used directly indicates the total hardness in \u003cstrong\u003e°dGH\u003c\/strong\u003e. For example, five drops represent a result of 5°dGH.\u003c\/p\u003e\n\u003cp\u003eOne 15ml bottle provides testing capacity for approximately \u003cstrong\u003e420°dGH\u003c\/strong\u003e, making it a practical option for regular aquarium and pond water monitoring.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cp\u003e• Brand: Sera\u003cbr\u003e• Product Name: GH Test\u003cbr\u003e• Product Type: Aquarium and Pond Water Hardness Test\u003cbr\u003e• Volume: \u003cstrong\u003e15ml\u003c\/strong\u003e\u003cbr\u003e• Measures total or general hardness (GH)\u003cbr\u003e• Suitable for freshwater aquariums and pond water\u003cbr\u003e• Testing capacity of approximately \u003cstrong\u003e420°dGH\u003c\/strong\u003e\u003cbr\u003e• Simple drop-count testing method\u003cbr\u003e• Each drop represents \u003cstrong\u003e1°dGH\u003c\/strong\u003e\u003cbr\u003e• Clear color change from red through brown to green\u003cbr\u003e• Helps select suitable fish according to water hardness\u003cbr\u003e• Supports healthy fish keeping and successful breeding\u003cbr\u003e• Ideal for routine water-quality monitoring\u003c\/p\u003e\n\u003ch3\u003eDirections for Use\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cp\u003eShake the reagent bottle well before use.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eRinse the measurement vial several times with the water being tested.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eFill the vial to the \u003cstrong\u003e5ml mark\u003c\/strong\u003e and dry the outside.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eAdd the reagent one drop at a time, gently shaking the vial after every drop.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eContinue until the color changes from red through brown to green.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCount the drops used.
