Pool Problems

Chlorine Demand

When pool contaminant levels get too high, your usual dose of chlorine doesn’t get the job done. Pool maintenance professionals refer to this phenomenon as “chlorine demand,” or “chlorine lock.” The solution is often more chlorine, but how much is too much? SENSE makes it easy to deal with chlorine demand—without irritating the eyes and skin of your guests.

Never deal with chlorine demand again.
