Biohome Plus ULTRA Filter Media (2 sizes)

Biohome Plus contain trace elements, which helps speed up colonization of the media by beneficial bacteria. The trace elements are responsible for the reddish colour of the media.Because the available surface area is much larger than that of other media, using Biohome filter media in your filter will increase efficiency of your filter. Please make sure to provide sufficient mechanical filteration to prevent Biohome media from clogging with debris.Biohome is a sintered glass filter media made of heat treated silica sand. It can be used as a biological media in canister filters, power filters, internal filters and sumps. It has an enormous surface area, which allows it to house large amounts of beneficial bacteria in a very small space. The surface of the media gets colonized by two types of aerobic nitrifying bacteria – Nitrosomonas and Nitrobacter. The first converts ammonia (NH3) into less toxic nitrites (NO2) and the latter consumes nitrites (NO2) and excretes nitrates (NO3). Biohome contains a protected labyrinth of tunnels that are occupied by anaerobic bacteria (denitrifying bacteria), which breaks down nitrates (NO3) into free nitrogen.
