I finally got a second to get water tested at PS:
TC 4.0
FC 4.0
CC 0.0
pH 7.6
TA 100
CH 250
TA 100
TDS 750

Langlier Index 0.0 (what is this?)
Sequestrant 5

Any thoughts from the pros?

When I look super closely at the top surfaces of the spa and pool steps it kind of looks like the surface is slightly more pited and all most porous looking then when the pool was brand new. Is this normal (and I might be imagining this) . I can only see this when water is perfectly still and full sun. I don't see the signs of visible dust when I brush the pool like I did when the surface was new and marcite was curing.
