Jump start and speed cycle your marine aquarium with our pre-seeded bio media. Each item is matured in one of our long-standing cryptic raceways containing a diverse blend of natural live rock for a minimum of two months to supply you with an excellent base of various bacteria for nitrification and denitrification. As an added benefit, these will contain beneficial microfauna. Each Ultra Porous Ceramic Bio Media Sphere can stabilize up to 18 Gallons. This is a must with today’s man made and base rock that are primarily used to start reef aquariums. Wild Reef Pre-Seeded Bio Media must be put in aquarium water upon arrival to maintain its live benefits.
Will include Biospheres (1-1/4" Sphere Size)
