Whether you use a salt system or regular chlorine to disinfect your water, there are dozens of diseases that are resistant or immune to regular disinfection. But when pool water passes through the Solaxx UV1500A NUVO Above Ground Ultraviolet Water Sterilizer, these pathogens are eliminated by the same process used to sterilize surgical instruments. The NUVO Sterilizer is used in addition to chlorine and will instantly eliminate pathogens such as E. coli, salmonella, staph and streptococcus, giardia cyst, cryptosporidium and many other chlorine resistant pathogens. When water passes through the NUVO chamber, the result is the safest, cleanest water on earth… and all this is done in perfect safety for only pennies a month.
