I work in the industry for commercial pools. Neighborhood pools mostly. Will you pick up a pool that's what's replastered in January, but the company that did it did nothing for the start up. There's tons of scale deposits all over the plaster. It's just white plaster, nothing fancy. It needs to be acid washed, I just don't know whether or not we should drain it and acid wash it or hot start it. Any advice? The pool is 125,000 gallons.
