{"product_id":"blueshark-nitracore","title":"BlueShark NitraCore Biological Nitrate Removal Media 225g \u0026 400g","description":"\u003cp\u003eNitraCore is a specialised biological filter media designed to support natural nitrate reduction in freshwater and marine aquariums. Manufactured from a highly porous natural material, NitraCore creates the ideal environment for anaerobic denitrifying bacteria, helping to reduce nitrate levels and maintain a healthier aquatic ecosystem.\u003c\/p\u003e\u003cp\u003eUnlike traditional biological media that focus on aerobic nitrification, NitraCore is dedicated entirely to the denitrification process. As water slowly passes through its intricate pore structure, oxygen levels decrease, creating the conditions required for beneficial bacteria to convert nitrates into harmless nitrogen gas. This natural process helps control nitrate accumulation and supports long-term water quality.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePromotes natural biological nitrate reduction\u003c\/li\u003e\n\u003cli\u003eHighly porous structure encourages dense bacterial colonisation\u003c\/li\u003e\n\u003cli\u003eCreates anaerobic zones for effective denitrification\u003c\/li\u003e\n\u003cli\u003eHelps maintain lower nitrate levels in aquariums\u003c\/li\u003e\n\u003cli\u003eSuitable for freshwater and marine systems\u003c\/li\u003e\n\u003cli\u003eComplements biological media designed for nitrification\u003c\/li\u003e\n\u003cli\u003eLong-lasting and easy to use\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eSupports improved water quality and aquarium stability\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eAvailable Sizes\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\u003cp\u003e\u003cstrong\u003e225g (500ml)\u003c\/strong\u003e\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cstrong\u003e400g\u003c\/strong\u003e\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy Choose NitraCore?\u003c\/h2\u003e\u003cp\u003eExcess nitrate can contribute to algae growth, stress aquatic life and make maintaining water quality more challenging. NitraCore helps address this issue by supporting the final stage of the nitrogen cycle, allowing beneficial denitrifying bacteria to naturally remove nitrates from the aquarium.\u003c\/p\u003e\u003cp\u003eFor best results, NitraCore should be used alongside dedicated nitrification media, such as Blue Shark OxyCore, which handles the aerobic conversion of ammonia and nitrite.
