Because minerals are doing part of the sanitizing work, you can lower the chlorine level in the pool to 0.5 ppm. The combination of FROG minerals and 0.5 ppm chlorine is as effective as 1.0 ppm of chlorine alone.
With minerals reducing chlorine levels up to 50%, there is less cyanuric acid entering the pool in a season, therefore less build-up that can lead to chlorine inefficiency.
Instant FROG can work with any of these pools by providing an extra layer of protection against bacteria. Salt system users can turn their dial down and generate a lower chlorine level. Ozone and UV do not leave a residual in the pool so Instant FROG provides a steady bacteria fighting presence.
Minerals and 0.5 ppm of free chlorine make up a complete sanitizing system. The only other thing you need is a regular pool shock and some balancing chemicals. By not requiring borates, enzymes, clarifiers and other chemicals, you can actually lower the overall TDS in the water.
