KH acts as a buffer for the water's acidity (pH).\u003cbr\u003e\u003cbr\u003e Fish, plants, and the biological filter consume water hardness (KH). If, for example, little to no water is changed during the winter, the KH value will drop rapidly. KH also drops rapidly during periods of rain. This can have serious consequences for the fish, as the pH can suddenly drop sharply (PH crash).\u003c\/p\u003e\n\n \u003cp\u003e\u003cem\u003e\u003cstrong\u003ePlease note: These oyster shells are not suitable for hobby purposes such as making necklaces or painting oyster shells.\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\n\n\u003c\/div\u003e","brand":"Air Aqua","offers":[{"title":"Default Title","offer_id":47112974598431,"sku":"40235-10","price":27.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0808\/0323\/4079\/products\/oesterschelpen-emmer-air_aqua.jpg?v=1698401335","url":"https:\/\/vijverleven.nl\/en\/products\/oesterschelpen-in-emmer","provider":"Vijverleven","version":"1.0","type":"link"}
