Hello! I’m a brand new pool owner and this is my first time posting here so bare with me. I am having calcium build up in a few spots in the grout on our waterline tile. Is there anything I need to pay closer attention to as far as water chemistry to help with this? Or is this just a given? I test water daily.
Pool filled: 5/11/22
15k gallons
Micro fusion pebble
VS pump runs on high from 6-8am then low 8am-3pm
Location: northern CA
Readings as of 9:00am this morning
FC: 3.5
CC: 0
TA: 70
CYA: 40
PH: 7.6 (I usually target to keep around here)
CH: 230
Temp: 86 (gets about 89-90 by afternoon)

Your numbers are surprisingly good for CA water. You're up north so perhaps that is why, but your pH, TA, and CH are in a great place. Can you confirm which test kit you are using? The white product I'm seeing in the grout line may be efflorescence. Are there any water features near that area in the pic?
