Dosing recommendations: Divide the required amount by 3, adding 1/3 every 6 hours to prevent cloudy water. Pre-dissolve the 1/3 into a clean plastic bucket with clean fresh cold water. Pour the solution around the perimeter of the spa with the filter pump running. It is important that only cold water is used for dissolving this product as the reaction between the water and the product results in heat being generated.
