Like all biorbs, the biOrb 105 uses 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. To maintain your biOrb 105 all you need to do is simply replace the filter cartridge every four weeks and change a third of the water. The aquarium itself is made from acrylic which is ten times stronger than glass. You can keep larger species of fish in your biOrb 105 - go tropical or marine - and still enjoy the benefits of an aquarium which is simple to look after. 

MCR Lighting

Now you can enjoy the magic of multi-coloured lighting in your biOrb at the touch of a button. Simply choose your favourite colour or scroll through the entire spectrum of light

What's more, it is an automatic setting which simulates a natural light cycle for your fish. An inbuilt timer phases the light through a 24 hour period from daylight to moonlight and back again. Simply choose from the 8, 10 and 12 hour daylight settings and the MCR light will do the rest. You can leave it running 24/7, so if you are late home or away on holiday your fish's routine is not disturbed.
