What can cause Foamy Hot Tub Water?

  • There are several products that when added to water can cause a build-up of foam.

This will, in turn, allow for excessive foaming. Low calcium levels (soft water) can be damaging to the hot tub or spa itself. Low levels are, however, rare and one need not adjust those levels in a spa regularly.
