Pool surface has started becoming rough in last few months. Looking at the forums, I think this might be due to Calcium Scaling. I am attaching few pictures and my current pool chemistry. Can you please advise on how to control this. Thanks.

Thanks for the quick response. I use TFTestKit for measurements.
For few months, my PH was higher (8.2-8.6) and only recently I started adding Muriatic acid to get it lower. Also, pool water temperature is generally 80-85F (we have solar heating). I just started using pool math app and it shows higher temperature can increase CSI.

The high pH is a concern.

Use Poolmath to determine CSI. Keep your CSI between -0.6 and -0.3 for awhile. See if the roughness dissipates.
