Oase Hel-X 13 Biological Media, 20 Liters

Oase Hel-X 13 Biomedia is a biological media used in the ProfiClear Premium Compact Filters and Modules.

Biological filtration by colonies of beneficial bacteria remove toxic ammonia, ammonium and nitrites. Hel-X Bio-media has a huge ratio of protected inner surface versus exposed outer surface so the agitation caused by the turbulent water does not damage the bacterial colonies inside the media. This keeps colonies clean and active without a loss of decomposition capacity.
