The ultimate pool surface protection for superior scale, stain, and scum control and removal. New Synertec polymer technology provides unsurpassed surface protection without phosphates and acids. Beautec also removes existing scale buildup on tile and salt cell generators without scrubbing and use of harsh acid cleaners. Metal stains due to iron, copper, and manganese are strongly sequestered to prevent surface damage.
