The other day I was servicing a Hot Tub, and when I added ph Increaser the water became cloudy. I'm wondering if anyone has any idea why this might happen. The Hot Tub has a nature 2 sanitizer, and I suppliment that regularly with Oxy Shock and granular chlorine. pH and Total Alkalinity are checked and adjusted weekly, and the filter is cleaned weekly. This was an instant reaction as soon as I put the pH increaser in, I could see the water clouding up.
I'm suspecting it could be related to hard water. Increasing pH could result in the precipitation of CaCO3. Is this the case, or is it something else?
