It is suitable for new set-ups looking to mature quickly, as well as established tanks that need a bacterial boost following maintenance or medication.\u003c\/p\u003e\u003ch3\u003eWhat It Does\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eIntroduces beneficial nitrifying bacteria directly into the aquarium\u003c\/li\u003e\n\u003cli\u003eAccelerates the aquarium maturation period, allowing fish to be introduced sooner\u003c\/li\u003e\n\u003cli\u003eActively reduces toxic ammonia and nitrite concentrations\u003c\/li\u003e\n\u003cli\u003eReplenishes bacterial populations after filter cleaning or substrate disturbance\u003c\/li\u003e\n\u003cli\u003eRestores biological balance following antibiotic or other chemical treatments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFormulation\u003c\/h3\u003e\u003cp\u003eTropical Nitri-Active is a 100% natural product, free from synthetic additives. It combines aerobic bacteria with facultative anaerobes — bacteria capable of functioning in both oxygen-rich and oxygen-depleted conditions. This dual-action approach ensures the nitrogen cycle operates effectively across different zones of the aquarium, including within substrate and filter media.\u003c\/p\u003e\u003ch3\u003eWhen to Use It\u003c\/h3\u003e\u003cp\u003eUse Tropical Nitri-Active when setting up a new aquarium to shorten the cycling period, or add it to an established tank after any event that disrupts the biological filter — including cleaning, partial substrate changes, or a course of antibacterial treatment. Regular use supports the natural self-cleaning processes that keep water parameters stable long-term.\u003c\/p\u003e\u003cp\u003eFor any keeper who has dealt with an ammonia spike or a stalled cycle, having Tropical Nitri-Active on hand is straightforward insurance. Consistent biological filtration means more stable water chemistry and less intervention over time.\u003c\/p\u003e","brand":"Peregrine","offers":[{"title":"Default Title","offer_id":54146867691857,"sku":"1VTT025","price":12.08,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0963\/0403\/8225\/files\/1VTT025_1.jpg?v=1782486908","url":"https:\/\/viperia.co.uk\/products\/tropical-nitri-active-100ml","provider":"Viperia UK","version":"1.0","type":"link"}
