Pat,

I opened my 2 year old 18,000 gallon gray plaster pool this year and found the same problem that you have - very rough surface. I have always been meticulous about my pool plaster. When I closed it, the water was in balance and the plaster baby bottom smooth. Now it is a disgrace. I have been running it acidic for the past 2 weeks and brushing and sanding. The steps are a bit better, our swimsuits are finally safe. The sides are still very rough. The appearance of the plaster is just not what it used to be, not to mention the feel of it. The service company who closed the pool said the PH must have gone up too high over the winter, causing scale.

I am curious... are you going to acid wash and sand the pool yourself? Is this a difficult process? Let me know how you make out. I am trying to decide what to do.

Thanks
Mary
