This white line appears just above the water line in my hot tub and is most prominent when the hot tub is on I.e. The water is hot - see photo
I do not see this around my pool.
Test results from today:
pH 7.7
FC 6.5
CC 0.0
CH 225
TA 80
CYA 60
Can someone advise what causes this and how to get rid of it?
Thanks
Dave
