Lo-Chlor's solution for seriously cloudy water!
Clear water is free of particulate matter. When particles of dust, dirt and other matter become suspended in clear pool water the water takes on a cloudy appearance. The degree of cloudiness is determined by the amount of suspended matter. Normally, the filtration system will remove suspended matter and maintain good water clarity.
A clarifier is designed to be used with a filter system, so particles coagulate in the filter. A flocculent is NOT to be used with the filtration system as the filter may clog. Flocculents are formulated to drop particles to the bottom of the pool, so they can be vacuumed away.
When using Knock-Out in water containing rich concentrations of positively charged ions (salt-water pools) be aware that the overall floc size is reduced. This will result in a floc of lighter appearance and intensity than might otherwise be anticipated. Salt water pool applications may require a second treatment or a double dose.
