Customers say
Customers find the pool shock treatment works quickly and effectively, making their pools clean and clear, with one noting it’s gentle on skin. They appreciate its reliability and consider it good value for money, and find it simple to use. The product receives mixed feedback regarding algae removal and chlorine levels – while some say it keeps algae under control, others report their pools turning green, and while some find it helps maintain chlorine levels, others say it doesn’t contain enough.
