How often should I shock my hot tub?

Treat an actively used hot tub no less than weekly, adding another dose following a party or any heavy bathing session.

What is the difference between chlorine and non-chlorine shock?

A chlorine shock produces a strong disinfecting rise in free chlorine. The non-chlorine alternative oxidises waste without that rise, which permits earlier bathing.

Can I shock and balance on the same day?

First correct pH, allow one hour and then apply shock. Leave the cover open throughout treatment to release chloramine gas.

How long should I leave the cover off after shocking?

Allow at least 30 minutes. Closing earlier retains chloramine vapour that can attack the shell, pillows and headrests.

When can I get back in after a shock dose?

Return when free chlorine measures under 5 ppm. With circulation running, routine maintenance shock normally takes 1 to 2 hours to reach that level.
