3rd Step

If you do not have access to soft water, you have two choices. One is simply use a lot more HTS pH Up or HTS pH Down, depending on whether your pH is too high or low.

If your pH is off, its far more likely that its too high out of your tap. If so, you can also use a very small amount of muriatic acid, the same as used in pools to lower pH. However, your spa is much smaller than a pool. When I say a “small amount”, I’m literally speaking of no more than a tablespoon at a time.
