Copper and Silver ions are naturally occurring minerals that have anti-microbial properties, and have the power to treat water and containers. Does not contain chlorine and treats water for both bacteria & virus germs without having to rotate the water.

This is a product that everyone has been waiting for. A naturally occurring product that would enable us to take care of our stored water without the use of chlorine. Biofilm defender uses the latest technology to keep both copper and silver ions in a suspended form for many years. Both Copper and Silver have anti-microbial properties and attack germs that typically infect our water supply, water storage containers, or water filter media that filter our water. Many times a slimy film called bio-film grows on surfaces that come in contact with water and tends to shelter and protect bacteria and other germs from being destroyed even with chlorine. BioFilm Defender attacks this bio-film and exposes the germs to the copper and silver to be treated This patented process enables water to be stored longer and with less concern about contamination that ever before. One 2 oz bottle of our H2O ResQ treats up to 330 gallons of tap water (two WaterPrepared tanks).
