I realize the site is slow this time of year and am not in a big hurry for assistance.

I live in Arizona so the risk of floating the pool is non existent. It sat empty for 6 month while I did a back yard remodel about 7 years ago.

The plaster is not really in bad shape it's more a cause of shoddy work by the company I hired to re plaster it a few years back. It has areas with rough spots that the algae has taken hold in. I've held the pool at shock level for quite a while with no results so I'm going to try the bleach and dry out approach before spring.
