American SPS Nexa Chlor Spa Sanitizer
Nexa Chlor automatically purifies spa and small pools. It uses a very low concentration of sodium chloride (mineral salt), and converts it into free chlorine that treats algae and bacteria in the pool or spa. After this treatment, the chlorine reverts back into mineral salt. Earth friendly and energy efficient. Easy to operate...simply plug into standard GFCI outlet and place cell over the edge of the pool or spa. One year limited warranty.
