SpaGuard Lo'N'Slo slowly lowers pH to help prevent scale build-up, cloudy water and eye irritation from high pH or high total alkalinity.

SpaGuard Lo'N'Slo

To use Lo'N'Slo:

If the pH rises above 7.6, add Lo'N'Slo with circulation running and aeration off.

Determine the amount of Lo'N'Slo by performing an acid demand test in a BioGuard test kit or follow ALEX recommendations.

If you are having difficulty controlling the pH, test for total alkalinity and adjust as necessary or use Perfect Balance.
