SilkBalanceTM Was formulated with a unique technology that immediately begins to adjust the water's properties, removing excess minerals and metals, which if allowed to build up over time can be detrimental to filters and pumps. It was also formulated to be mild on your skin and contains mineral salts that leave your skin feeling silky smooth and invigorated. It does not leave a lingering odor of strong chemicals but rather a clear refreshing wonderful water scent Cleaning Your Spa Equipment SilkBalanceTM Clean Start a cleanser that cleans organic deposits and cleans or removes dirt, soil and inanimate organic particulates from plumbing systems. The only purge product that will not create foaming residue that would require multiple flushes to remove. It will leave your spa with a fresh and clean scent. We highly recommend using Clean Start for previously used spas prior to starting with the SilkBalance water conditioning program. SilkBalanceTM will extend the lifetime of your spa equipment components by breaking down existing lime scale deposits the first time you use it and then continuously inhibiting further build up that comes into spas from tap water. SilkBalanceTM instantly changes the properties of the spa water by making it difficult for existing lime scale to attach itself to anything in the spa and then releases it to be captured by the filters. Improving and Maintaining Performance By eliminating existing limes scale deposits and continuously inhibiting the excess calcium build up it allows water to flow freely throughout the spas' internal plumbing and jet fixtures.
