The biOrb CLASSIC features a 5-stage filtration system bigger than any tanks its size, and, in fact, larger that many twice its size. The biOrb CLASSIC’s filtration system works as follows:

  1. The air powered filtration system creates dynamic water flow and constantly changes the surface water, maintaining oxygen saturation.
  2. The circular flow of water collects fish waste on its way to the bottom.
  3. The filter then pulls the waste through the ceramic media at the bottom of the tank, where natural biological filtration absorbs some of the toxins. The newly oxygenated water also feeds good bacteria.
  4. The remaining waste is trapped in the filter sponge and the water continues through resin particles and natural stabilizers to remove the remaining toxins and help keep the pH levels stable.
  5. The clean water is oxygenated as it moves up the bubble tube so that the cycle can start again.

Both the lighting unit and air pump are low voltage and come with a 12-month guarantee.

The 28-gallon biOrb fish tank features an Intelligent LED Light, which also uses a low voltage LED light that plugs into the transformer. The Intelligent LED Light uses an inbuilt timer which cycles through sunrise, daylight, sunset, and moonlight over a 24-hour period.


The biOrb fish tank is constructed from acrylic which is 10x stronger than glass, as well as 50% lighter and 93% clearer, making for a much better viewing experience.
