The BiOrb aquarium is perfect for a beginner aquarist who wants a bit of a helping hand with setting up an aquarium or for people who don't have or don't want to spend the time buying all the required aquarium peripherals and maintaining the tank afterwards.

The unique built in five stage filter system minimises maintenance and keeps the tank water crystal clear making the whole thing look stunning. In addition they come with special ceramic 'gravel' which is porous and is able to hold a very large number of the friendly bacteria responsible for keeping ammonia and nitrite levels down. Maintenance wise all that is necessary is to change the filter cartridge when specified and to change some of the water every month to keep down the nitrate levels.

The biggest thing to remember is that the BiOrb range is totally made up of relatively small aquaria compared with normal size glass tanks. It is easy to put too many fish into these tanks in spite o the very efficient filter and aeration systems. Even one goldfish in a baby BiOrb is too much and of course fish grow and can easily outgrow your BiOrb aquarium. Some fish, whatever their size are just not suitable, they may need lots of plants or more water than the BiOrb can provide.

To summarise, the advantages of these tanks are:

• Good design and excellent lighting effects consistent through the whole BiOrb range

• They have a small footprint

• Everything you need is in the box including full instructions

• The BiOrb range is made from plexiglas acrylic which is ten times stronger than glass

• They come with an easy change filter cartridge

• The 5 stage filtration system keeps the fish healthy and reduces maintenance

and some disadvantages:

• They are not cheap

• The small size of these tanks limits your choice of fish and their numbers

• The globe shaped tanks have a small top opening which can make cleaning of the inside wall a bit tricky

Conclusion

With the special intelligent LED lighting, the unusual shapes and the vigorous aeration of the water the BiOrb aquarium range looks amazing. For an easy entry into the wonderful world of aquarium keeping they can certainly be recommended.
