So, I had my pool resurfaced with pebble tec in july. my water looks crystal clear, but when I brush at night I can see cloudiness brushed in front of the light. I have a Polaris Freedom robot vac and every morning I put it in it collects a lot of white dust that feels like sand. So I went to the pool store and they added a touch of acid to the dried out dust from yesterday and it foamed up immediately.
is that calcium hardness? There is no white showing up on the pool... its dark blue so I would see it.
my calcium seems to be test around 300-400 - Welcome your thoughts?
Salt pool - 3600
Chlorine - 4.8
PH 7.6
alkalinity - 69
CYA - 54
