All biOrbs use special ceramic media to provide biological filtration, which has a surface area equivalent to the size of a football pitch. Any excess waste is collected and held in a filter cartridge at the base of the biOrb.
For your peace of mind, the lights and pump are low voltage and are backed by a 12 month guarantee. The aquarium itself is made from acrylic which is ten times stronger than glass.
You can keep an impressive collection of fish in your biOrb and still enjoy the benefits of an aquarium which is simple to look after.
Heater sold separately.
