re: Need Pool Repair Advice

If you are selling the house, get the pool replastered. You can't patch that or cover it up and get full value out of the pool in a sale. Any sophisticated buyer will factor the cost of replastering into the sale price. On the other hand, replaster the pool and it will look great and you can factor the cost into the asking price.

As for the surface falling apart, the issue isn't ph, it's calcium hardness. If you don't monitor the hardness levels, the aggressive water will leach calcium from the plaster, causing the surface to disintegrate. Calcium hardness is the most important factor in taking care of pool plaster.
