Don't be fooled by the small package. This highly-concentrated Serum is an innovative, unmatched and revolutionary natural cleaner designed to clean out your hot tub pipes. Essentially, spa contaminants inside your pipes, surface grit, oils and other hard to remove substances are broken down by the gel and suspended in spa water after the initial cleanse. This initial "cleanse" is a one-time requirement to get rid of the previous build-up on the shell and in the pipes. Even brand new hot tubs must be purged. You won't believe all the manufacturing byproducts that can be eradicated.
The clarifier in the gel will allow the filter cartridge(s) to efficiently entrap these substances. This product can be used with Di-Chlor, Ozone, Bromine, Chlorine, Nature2, Frog, Bacquaspa, Ionization or any other sanitizer. Best of all, you will need less product or "run time" to keep the water looking, feeling and smelling great. Follow the written instructions as written on the container and you will see drastic changes in the water quality after only a few days.
