What chlorine level should my spa be at?

First, tell us how you treat your spa: the installed salt system, the mineral purifier system, or chlorine granules.

We encourage the salt system or the mineral purifier.

With either the salt system or the mineral purifier, we don't try to keep the chlorine level up in the OK range.

If you use only chlorine granules, you typically add chlorine after getting out of the spa.
