This kit is all you need to successfully maintain your biOrb aquarium
The disc filter cartridge in your biOrb should be changed every 4-8 weeks*. Three sealed cartridges are included in the kit, along with a special cleaning pad for removing dirt and algae from the inside surface of the biOrb. The three sachets of water preparation chemicals help to prevent any issue when carrying out a regular partial water change.
Most aquariums have filters with several compartments containing different types of filter media which need to be carefully cut, measured and changed. Changing too much or too little can result in water quality problems. In the Service Kit, this has all been done for you, so you just have to replace the filter cartridge and don’t need to worry.
