{"product_id":"ntlabs-ammonia-test-kit","title":"NTlabs Ammonia Test Kit","description":"\u003cp\u003eThe NT Labs Ammonia Test Kit gives you a simple, reliable way to check ammonia (NH₃\/NH₄⁺) levels in freshwater or marine aquariums — especially critical when cycling a new tank, adding fish, or after filter maintenance. Because ammonia is invisible yet highly toxic to fish and invertebrates, even small amounts can cause stress or illness. The test kit uses a liquid-reagent method: add a small water sample, apply the reagents, wait about 10 minutes, then compare the resulting colour to the supplied chart. A yellow result means zero ammonia, which is ideal — any green tint indicates ammonia presence and potential danger. Regular testing helps you catch ammonia spikes early and act quickly, for instance with water changes or filter boosters, to keep your aquarium environment safe and healthy.\u003c\/p\u003e","brand":"Marine Fish Shop Online","offers":[{"title":"Default Title","offer_id":52011296620885,"sku":null,"price":10.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0967\/2278\/0501\/files\/ammoniatest.webp?v=1764623356","url":"https:\/\/marinefishshop.uk\/products\/ntlabs-ammonia-test-kit","provider":"Marine Fish Shop Online","version":"1.0","type":"link"}
