5/5 (Unbelievable)

The original biOrb and still as popular as ever. The biOrb 30 is a healthy home for fancy goldfish or small tropical fish. It comes in a range options to suit everyone. 


biOrb 30 combines classic good looks with high tech filtration. 

Most aquariums use small box filters and/or smooth gravel which easily clogs with dirt. Like all biorbs, the biOrb 30 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 30 all you do is simply replace the filter cartridge every four weeks and change a third of the water.

Two light options exist for the biOrb 30, a standard LED light and an intelligent light which uses long life LEDs to automatically replicate a natural 24 hour light cycle. 

For safetly and 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 enjoy all the technology of an advanced aquarium set up, supplied in one box. The biOrb 30 is the perfect aquarium for anyone new to fish keeping.
