Greetings from Sacramento .

I had a calcium build up and it was from me taking care of my own pool for the last 4 years. It was only a matter of time before some issues started happening.

Water was sparkling but started getting some build up on my steps this past winter. I was able to use the vinegar test to determine it was calcium. Lowered the ph and it started coming off with some light brushing@@

This forum is amazing!!
