Hot tub water that has a very high pH level out of the recommended range may leave sand-paper like deposits on the shell or calcium carbonate deposits which in extreme cases can coat the entire spa. 

Use pH Up to make the water more basic or pH Down to make the water more acidic

The recommended range is 7.2 - 7.8. Some say 7.4-7.8 while others say 7.2-7.6. Check pH with spa test strips or a water test kit.

In this range, both the spa user and equipment are protected. If the pH levels are not in the acceptable range use pH Up to make the water more basic or this product, pH Down to make the water more acidic.

DIRECTIONS
To lower pH of water, follow the recommended dosages on the container. Retest in 1 hour, add
accordingly until proper pH is attained. Proper pH should be maintained between
7.2-7.6.
