Thank you for your reply. I shocked it, but foam remained after few hrs. So I decided to deep clean/drain/refill -because of the sticky scum. The clothing detergent left on clothes was accident.
I'm brand new to all of this. Less than a week. I don't quite understand the whole shock -with chlorine or bromine. I was under impression chlorine shock is for a deep clean, and can hurt pipes if used too much. And bromine is for every week/after use?
I got a water read out from spa store. Followed directions for chems they suggested 1x week. Add stain/scale, then water clarifier, then alk increaser, then pHdecrease, then chlorine concentrate all amounts written on print out. All chems had wait times after adding each one. Thank you.
