It’s powerful formula and ease of use has made it the number one choice of pool professionals for almost 40 years. Using Yellow Treat is not just powerful, it is also easy to use! Just add one capful per 10,000 gallons of pool water, brush affected areas, then shock your pool.

  • Doesn’t contain copper or silver so it won’t leave stains.
