This kit is all you need to successfully maintain your BiOrb aquarium over a 3 month period. 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. The kit also contains a replacement airstone, which should be replaced every 3 months in order to deliver the very best performance from your filter and prolong the life of the air pump. Additionally, the box contains an easy to follow step-by-step guide with all the necessary instructions.
