My friends pool has developed a very rough surface over the past two years. I do not think he managed the chemicles well and maybe let the PH run too high as well as used unfiltered well water to top off on a regular basis. No agents were used.
Anyway he is now looking at draining, acid wash, and using the Aquaglide system to polish and remove the deposits
Does this sound like a good solution -- ANY ideas would be appreciated.
This is a 30k gal plaster pool/grey that is about 5 years old.
