So the next thing that happens is, now that your water stays so ridiculously clear, the old plaster looks worse, because now you can see it completely! This is what happened to me, and then I eventually was driven to look for an drain and acid wash.
So while TFP has saved me tons of money, it has also "cost" me tons of money [read on] ;-)
So now that I figured out I could "magically" do what I was paying my pool guy to do, I thought, "if I could just keep the PH in check, I'd stop, and maybe even be able to reverse all this calcium depositing [that may be what you see by the way].
So that led to adding automated acid dosing.
That also led to replacing my old SWG, which was quite a challenge due to the newness of the design.
So now my water was both crystal clear, and it was staying that way!
So with this super clear water, now I had to clean my plaster. So that turned into one heck of a project [ask Brian!].

With all that, I couldn't be happier. I check my chemicals once a week, empty the robot, clean out the skimmer [well just throw out the hair net], and scrub the sides where the robot doesn't get them.
And it just stays nice! Better than when I was paying a lot of money for someone else to do a poor job of it!
Anyway, the reason for the long story is to look into acid washing if all that stuff is calcium build up. Then keep your CSI slightly negative and it won't come back.
You can't Acid wash plaster too many times though.
(See, I've been doing my reading!)
