So the other day when I checked water it was FC at 7.0 and PH @ 7.2 and the water literally sparkled.
It has stayed clear and algae free on plaster, but seems to have a bit of opacity to it. Are there particular values asssociated with sparkling. Pool store guessed without testing that it was TC, but never has been high.
Planning a pool party early next month and if I could get down the sparkle bit, that would be sooo cool.
