White spots on tile

[joel98z]

I have found these little white spot showing up lately on my tile. They wipe off very easily with my hand but re-appear a few days later. To me they look like little salt deposits but not sure and, should I be concerned?

Most current testing results
FC: 8.5 (Last month Avg 7.2)
PH: 8.0 (Last month Avg 7.8)
TA: 50
CH: 450
CYA: 70
SALT: 3200 (Last month AVG 3200)

Likely calcium scale. Water is imbibing up the grout and evaporating.

You only test your chemistry once a month? That is a recipe for disaster eventually.

Is calcium scale something to worry about?

I test my FC, and PH multiple times weekly.. The others I could do better with..

With a CH of 450, you will get scale in evaporative environment. Not much you can do. Clean it off. Use a dilute muriatic acid if necessary. Use eye protection if using muriatic acid.

Thanks! For good measure I just went and ran a full set of tests..
