Details on the XERO RO Guardian

• Keep your RO Membranes protected when you won't be using your system for a few weeks to a few months. 
• The XERO RO Guardian prevents bacteria from growing on your RO Membranes while they sit inactive.
• Mix the RO Guardian with 1 gallon of pure water or RV anti-freeze and pour it right into the RO Housing over the membrane. Leave it in the housing until you're ready to use your system again. 
• It easily rinses off your RO membrane once you restart your system.
