The BioBoost media has a five-year warranty.
The rubber membrane diffusers integrated into the BioBoost media have a one year warranty. If the bubble pattern looks weaker or different, it is advisable to replace them. They are very inexpensive, approximately $25.00/diffuser and can be ordered through our company.
Any auxiliary equipment used to run BioBoost (including but not limited to compressor, airline, etc.) has a warranty established by the manufacturer, typically lasting anywhere from 1-3 years.
