Bubble Bios are the world's first Aquarium Moving Media Filters based on industrial MBBR (Moving Bed Biofilm Reactor) technology, which is the recent technology used at the aquaculture system.
All Bubble Bios have cleanable air diffusers which can give fine bubbles into the filters powered by aquarium air pumps.
These air bubbles can give essential oxygen to the filter media and also make moving filter media always rolling which can make auto cleaning. As a result, Bubble Bios will do excellent biofiltration and give convenience to you.
All models have bottom filter sponges, but Stand Up Models have fine gravels furthermore in the bottom parts, so these can be sit down naturally and do double physical filtration also.
