I am moving into a home with an existing plaster pool and I want to do a drain and acid wash before refilling and setting it up. There is currently only a few feet of water in the deep end, which is a swamp. The majority of the pool walls and bottom (that can be seen) seem that they could greatly benefit from an acid wash to clean the surfacing before filling it...but how do I know whether the plaster is okay for doing the acid wash?
The overall appearance is good, at least in the sense that there is not cracking or scaling, as far as I can tell.
The 2nd thing that I'm wondering about is whether the pool could have a leak since it seems that it should not be as low as it is from evaporation alone...but the pool (and home itself) has been unattended for at least 6 months or more, but I don't know if that is enough time for this size of a pool to evaporate down to only about 2 feet (estimated) of water in the deep end.
