Here’s how a biOrb aquarium works

All biOrbs have a filter at the bottom of the aquarium. It’s where solid waste naturally settles. Put simply, the filter works where there is most to filter.

1. Air driven filtration system creates vigorous water flow and a constantly changing water surface. This maintains oxygen saturation.
2. The circular flow of water then collects any fish waste on its way down.
3. It draws the waste through the ceramic media where the natural biological filtration absorbs some toxins. The freshly oxygenated water also feeds the bacteria. 
4. Any remaining waste is trapped in the sponge cartridge. The water then passes through resin particles and natural stabilisers to remove toxic substances and keep the pH levels constant.
5. The clean water is then oxygenated as it flows back up the bubble tube to repeat the cycle.
