I just opened my pool after it spent its first winter winterized and covered. I'm afraid the surface of the Diamondbrite has become much rougher where there was water, and is still smooth like it was last year where there was not. In other words, if I slide my hand down the sides of the wall, its smooth to the touch until I get to where the water level was left at for the winterizing. Then it is quite irritatingly rough. Same thing on the steps- first one is fine, rest of them very rough.
The Vii cleaner is also picking up a lot of white sand, requiring frequent emptying of the bag because it fills up to the sand line and the robot begins to go upside down etc.
It seems undeniable that my plaster has suffered somewhat.
I'm assuming that this isn't a product failure, but I did check the pH and CL levels mid-winter and added acid and bleach. They were off but not horrendously off.
MY QUESTION(S) IS: is this typical of a brand new pool going its first winter and now should settle in? And what do I do now about the rough surface?
