Ziss Moving Bed Filter
The world's first aquarium filter with moving filter medium. Ziss Bubble Moving Media Filters are air driven filters which provide your aquarium with clean, but most importantly, healthy water. The filters stimulate the natural processing of waste substances in the water, so that toxins such as ammonia, nitrite and nitrate are converted in an organic way. An air pump is required to run this filter (recommend an Eheim Air 200 or equivalent).
