| Spa Water BalancersThe pH scale is 0-14 and is a measure of whether the water is acidic or alkaline. Water with a pH of 7 is said to be neutral, below 7 is acidic and above 7 is alkaline. For a Spa or Hot Tub the ideal pH level is between 7.2 and 7.6ppm, when the pH falls below this level you will need to increase it: pH Plus is the recomended product to do this and if you need to decrease it: pH Minus is the recomended product to do this. |  | Refine Results | | |
