{"product_id":"api-gh-kh-test-kit","title":"API GH \u0026 KH Test Kit","description":"Monitor and maintain your aquarium's general hardness (GH) and carbonate hardness (KH) with this essential test kit. Unstable pH levels often signal the need for KH testing—regular monitoring helps prevent stress in fish and plants while promoting healthy growth.\n\nThis drop-based test measures dissolved minerals (GH) crucial for fish osmoregulation and plant development, plus buffering capacity (KH) to keep pH stable. Simply add drops until the colour change occurs, count them, and adjust water hardness as needed using products like crushed coral or calcium carbonate.\n\nPerfect for replicating natural water conditions and maintaining a thriving aquatic environment.","brand":"Api","offers":[{"title":"Default Title","offer_id":48133570003170,"sku":null,"price":31.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0066\/1284\/4602\/files\/api-gh-kh-test-kit-1.png?v=1789017574","url":"https:\/\/reefsecrets.com.au\/products\/api-gh-kh-test-kit","provider":"Reef Secrets ","version":"1.0","type":"link"}
