Hoping someone here might be able to offer suggestions for a longstanding problem with my hottub.
There are tiny crystals on the inside of my hottub. I have been told they are calcium and to add 6-8 gallons
of vinegar to water (which removes the crystals) and then to drain the tub. I have probably done this at least 10 times now.
Each time I drain the tub down, put in fresh water (not well or watersoftener water). The sides are clean with no crystals
for about a day, then by day 2, the crystals are back on the walls. I add vinegar, they dissappear, I drain, refill, they come back.
Also tried adding spa purge as someone recommended, actually tried this twice this past week. But that has solved the problem
Any other ideas, this is so frustrating, as I just don't know what to do. The hottub justs sits unused due to the crystals.
