Chitosan is renowned in water treatment for its remarkable properties, including adsorption, coagulation, and flocculation capabilities. Clears cloudy water fast Dual-action hot tub clarifier Environmentally friendly formula Application Instructions 1. Apply Spa Sparkle directly to your hot tub water whilst the pump(s) are turned on to aid distribution. 2. Hot tubs treated for very cloudy water may require filters to be cleaned a week after treatment. 3. When hot tub water becomes saturated with dissolved solids (TDS), AquaSPArkle Spa Sparkle may become less effective. At this stage, the hot tub should be drained and refilled with fresh water. Litres Gallons Initial Dose Weekly top-up 1,000 220 50ml 25ml 1,500 330 75ml 38ml When Spas become saturated with dissolved solids (TDS) then AquaSPArkle Spa Sparkle may become less effective. Under these circumstances, the spa water should be changed. Always read the instructions on the container prior to use. Confused about your hot tub water chemistry??
