BiOrb Service Kit 6 Pack

BiOrb Service Kit - 6 Pack

The filter cartridge works like a waste bin, trapping dirt.  Once full, it should be thrown away and replaced with a new one every 4 to 8 weeks.  A partial water change of 30% should be carried out at the same time.

Contents of each BiOrb Service Kit:

• Replacement filter cartridge
• Algae cleaning cloth
• Sachet of water preparation chemicals
