I just purchased a home with a 17,500 gal plaster IG pool, simple rectangle, steps in the corner. It's in decent shape, but my CYA is sky high; between 120 and 155 depending on which test you trust. Between that and my very high calcium levels, I've decided to drain and refill the pool.
I know I want to do a visual inspection, I'm also going to replace the bulb and gasket on the light just because I can. I don't have a water table issue, the land slopes down behind my pool almost as deep as the pool.
Any other suggestions for maintenance or inspection while I have the plaster exposed?
