Cloudy water is it my filter?

No slime but just a rough texture.

Look at the pictures of the white or sand colored bumps -- those are the end point residue left after the algae is gone.

My k2006 test this am,
FC 2.5
CC 0
PH 7.2
TA 90
CH 90

I added more chlorine and 1 box of borax.
Water is crystal clear.

Looking good.

But if the roughness on your liner is calcium scale it would be better to keep your pH near 7.0, till the roughness is gone.

my latest test last night,

FC 4.5
CC 0.5
PH 7.2-7.3
TA 90
CA 90
CYA 45

the box of Borax didn't do very much as I added water and my fill water PH is 6.8 and FC of 2-3 ppm.
did a chock last night and its looking good this am. Very clear.
On the CYA its hard to not see that dot, how far should I be when looking down at it?

When testing CYA, hold the vial at waist level and have the sun at your back.

Just reopened my pool last week and got it cleaned and clear water within 3 days.
Filter is running good with the fix from last year.

Got it chocked to try to remove some dirt stain.
Water looks pretty good without adding any chemicals beside chlorine.
Is my CYA level of 40 ok Or I should bump it up?
