Up until about a year ago my pool ran at a ph > 7.8. The white plaster had a general greyish stain. A year ago I treated with the pink Scale-Tec liquid and began running my ph around 7.2-7.4. The stain slowly went away and the plaster looks good now. Pool is crystal clear. Since then I have had a fine white powder in my cleaner bag. It appears to be calcium carbonate since it fizzes vigorously with muriatic and fizzes pretty good with vinegar. Do I need to be concerned about high CH if the CSI is Ok? Is the white powder coming from the stain being removed or from the plaster itself? Do the Taylor and TPF CSI values usually not coincide? Thanks!
