Hi
Big fan of TFP and really appreciate all of the expert advice here.
Trying to decide whether to raise CH before closing?
But I'm not sure what I am seeing.....
The pool surface is quite rough - like sandpaper.
This pic is the top step surface from the beginning of the season.
Is this a plaster surface that has been damaged by etching?
Or is this a plaster surface that has been damaged by calcium scaling?
Or both?
The whitish areas seem a little smoother than the slightly darker areas, but do not seem to be raised above the surface of the plaster.
I assumed it was calcium deposits, so kept the CH a bit lower (150) - but managed the pH to keep the CSI close to zero. Over the season some of the whitish areas have disappeared.
But the pool surface is still rough.
Never seen a new plaster pool so I'm not sure what I should be seeing.
Thanks for any advice.
