The Hot Tub Serum Total Maintenance is added to your spa to remove biofilm. This is a crucial step in weekly maintenance to have the cleanest spa and spa water possible. It works to destroy bacteria in ways that sanitizers can't, reaching deep into the plumbing of the spa and preventing the chance of an accumulation of that sludge. This destruction of the contaminants in the water also allows for a clearer and softer feel while reducing the amount of sanitizer that is used up in your spa.

This is the 2L bottle of the Hot Tub Serum Total Maintenance.
