Aqua Natural Live Filter Media Biospheres Nano is a revolutionary pre-seeded biological filter media designed to instantly jumpstart the nitrogen cycle in new or established saltwater and freshwater aquariums. Made from highly porous, durable material, it provides an immediate home for beneficial bacteria that efficiently break down harmful ammonia and nitrite into less toxic nitrate, ensuring crystal-clear water and stable water chemistry from day one. Each 16 ounce can of this powerful media is capable of supporting up to 50 gallons of aquarium water, offering a massive surface area for extensive bacterial colonization. Its robust composition ensures it will not break down or dissolve over time, providing long-lasting biological filtration. It is perfectly suited for use in a variety of filtration systems, including canister filters, sumps, hang-on-back filters, reactors, and media bags. This live filter media is ideal for aquarists looking to quickly cycle a new setup, enhance existing filtration, recover from deep cleaning, or support a higher bioload. Unlike dry ceramic media that takes weeks to establish or temporary liquid bacteria additives, Aqua Natural Live Filter Media Biospheres Nano offers an instant and sustainable boost to your aquarium's ecosystem, allowing your aquatic inhabitants to thrive without delay.
