Spa Sparkle is an organic polymer, polisher and clarifier for treating spa water. It collects small particles, the cause of spa water cloudiness, and forms them into larger ones. These larger particles are then removed by your filtration system. Application Ensure that your filter has been cleaned prior to application and that circulation is on. Proceed in pouring 25mls of WAVE Spa Sparkle directly into the spa at capacity (1000L). Add to the spa water with the filtration system running and keep it running for at least 1 hour. After 12 hours check the filter cartridge and if required, hose down and remove the residual debris. Increase the frequency of this dose if your spa is used regularly. This product can be used daily and as a problem solver for a cloudy spa. The spa may be used immediately after treatment. Never mix with any other chemicals. Always wash your hands after using spa chemicals. Shake bottle before use. Keep locked up and out of the reach of children.
