How do I use CleverSpa pH Minus?
Test the pH of your hot tub water. If the pH of the water is higher than 7.6 then apply CleverSpa pH Minus as follows:

1. Pre-dissolve the required amount of CleverSpa pH Minus in a clean plastic bucket filled with warm water. Stir the solution until the granules are fully dissolved.
2. Ensure that your hot tub circulation pump is turned on before slowly pouring the solution directly onto the water surface.
3. Continue to run your hot tub circulation pump for 15 minutes.
4 Re-test your water and repeat dosage until a pH reading of between 7.2 and 7.6 is achieved.
5. Allow 15 minutes before using your hot tub.

Please Note:
• Test before use.
• Pre-dissolve and add to water.
• Leave for 15 minutes.
• Do not mix chemicals.
