When you use your hot tub, tiny particles of oil, deodorant, make-up, and other cosmetic products can wash off your skin and hair. Many of these particles are too small to be picked up by your hot tub filter, and over time will cause your water to look cloudy and dirty. Pro-Kleen Spa Clarifier causes these tiny particles to bind together so theyre caught by your filter, giving you crystal clear spa water instantly. Just 2 capfuls of Spa Clarifier can treat your entire hot tub! A little goes a long way, giving you more clear spa sessions for your money. Simply add 2 capfuls (50ml) of Pro-Kleen Spa Clarifier to your hot tub water and turn on your jets to allow it to circulate around your spa system. Thats all there is to it - youll notice your hot tub water looking clearer right away! Spa Clarifier gets to work right away, giving you crystal clear and hygienic hot tub water instantly. Combine it with Pro-Kleens Anti-Foam to neutralise foam on the surface of your hot tub for sparkling, clear jacuzzi water! By binding together small particles that contaminate your hot tub water, Spa Clarifier will dramatically improve the efficiency of your filter system. Spa Clarifier gives the same amazing results in most above-ground pools, spas, and hot tubs. ProKleen Hot Tub & Spa Water Clarifier Clears Cloudy Dull Looking Water 1 x 5L in Clear
