You will be amazed at the quick results these units provide. Back-wash time is reduced significantly, and chemical use such as chlorine can be reduced typically by 2/3rds to achieve the same free-chlorine levels. Back-wash cycles can typically be extended by 4x. Bacterial levels are typically reduced to nearly nothing, and algae growth and biofouling can be completely eliminated. Chemical staining and scum around the sides of the spa is drastically reduced or eliminated.
Designed specifically for Spas, Whirlpools & Jacuzzis, the W-63 will provide domestic users with the same benefits that our larger commercial "P" units provide for our commercial spa clients.
