{"product_id":"blue-shark-colony-rapid-cycle-118ml","title":"Blue Shark Colony Rapid Cycle 118ml","description":"\u003cp\u003eBlue Shark Colony Rapid Cycle 118 ml is a concentrated live nitrifying bacteria solution designed to establish biological filtration quickly in saltwater (or freshwater) aquariums. It introduces real nitrifying bacteria (such as Nitrococcus and Nitrosococcus for marine systems) that convert toxic ammonia and nitrite into less harmful nitrate, reducing the typical 6–8 week “cycling” period to just a few days. The 118 ml size is calibrated to treat approximately 45 L of aquarium water in one dose. For best results use with stable pH (marine: ~7.9–8.3), adequate alkalinity, good aeration, and avoid UV sterilizers or ozone during the initial cycle period.\u003c\/p\u003e","brand":"Marine Fish Shop Online","offers":[{"title":"Default Title","offer_id":52044877201749,"sku":null,"price":9.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0967\/2278\/0501\/files\/118ml.webp?v=1765227378","url":"https:\/\/marinefishshop.uk\/products\/blue-shark-colony-rapid-cycle-118ml","provider":"Marine Fish Shop Online","version":"1.0","type":"link"}
