In deze blog lees je waarom onthard leidingwater niet zomaar geschikt is voor je aquarium of vijver, wat er precies verandert in het water, en hoe je toch gewoon je vertrouwde leidingwater kunt gebruiken zonder je waterontharder te hoeven missen. Het korte antwoord: nee, vervang het water niet in een keer door onthard water. Vissen zijn gevoelig voor andere waarden dan waar een waterontharder om draait.<\/span><\/p>\n

 <\/p>\n

Heeft een waterontharder invloed op je aquarium of vijver? <\/span><\/h2>\n

Een<\/span> waterontharder<\/span><\/a> verandert de samenstelling van je leidingwater, en dat is relevant zodra je een aquarium of vijver hebt. Vissen zijn niet gevoelig voor de waarde die bij een waterontharder centraal staat (dH), maar wel voor twee andere waarden die daarbij meeveranderen: KH en GH.<\/span><\/p>\n

 <\/p>\n

Welke waardes zijn belangrijk voor aquarium- of vijverwater?<\/span><\/h2>\n

KH en GH zijn dus de waarden om in de gaten te houden, niet dH. Maar wat meten die twee dan precies, en waarom maakt dat verschil voor je vissen? Hardheid klinkt als \u00e9\u00e9n begrip, maar dH, GH en KH meten niet hetzelfde.<\/span><\/p>\n
