Proper pool water balance helps reduce skin and eye irritation. If the pH of your pool is above 7.6, Suncoast pH Minus is needed to help lower the pH. pH Minus can also be used to lower the total alkalinity. This product performs the same task as liquid muriatic acid.
Remember: never adjust your pH unless your Total Alkalinity is already in its ideal range (70-140ppm). Always check your pH levels before and after lowering your alkalinity.
