{"product_id":"ntlabs-phosphate-test-kit","title":"NTlabs Phosphate Test Kit","description":"\u003cp\u003eThe NT Labs Phosphate Test Kit lets you quickly and reliably measure phosphate levels (PO₄) in freshwater or marine aquariums — an important step in preventing algae outbreaks and maintaining stable water chemistry. The kit uses a simple liquid-reagent method: you add a water sample, apply the reagents, shake, wait five minutes for the colour change, then compare the result to the included chart to get a phosphate reading. A typical reef aquarium aims for very low phosphate (around 0.03 mg\/L) to support healthy coral growth and minimise nuisance algae.\u003c\/p\u003e","brand":"Marine Fish Shop Online","offers":[{"title":"Default Title","offer_id":52011294064981,"sku":null,"price":11.99,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0967\/2278\/0501\/files\/phosphatetest.webp?v=1764623165","url":"https:\/\/marinefishshop.uk\/products\/ntlabs-phosphate-test-kit","provider":"Marine Fish Shop Online","version":"1.0","type":"link"}
