Gold-N-Clear is a revolutionary water treatment formulation that turns pool water from cloudy to clear like magic. A unique color transformation from golden to blue occurs when Gold-N-Clear reacts with microparticles in the water indicating that the clarifying action has begun. Gold-N-Clear clears and brightens cloudy water by coagulating suspended micro-sized particles of dirt and other organic contaminants to masses large enough to be removed automatically by the filter. Regular use of Gold-N-Clear will help your filter do its job more effectively. Gold-N-Clear is a highly concentrated formula, contains no dyes, is non-toxic and 100% biodegradable.
