Since we'll be doing a follow up no drain acid wash, I would like to know the proper amount of acid to use. For a pool of 30,000 gallons advice has ranged anywhere from 6 to 12 gallons. There are a few remaining areas of original plaster dust that was not properly removed during the initial start up, and these areas are a bit stubborn. Most of the pool looks great, just want to get a nice uniform look throughout the plaster surface.
During round one we used 5 1/2 gallons, and I was told we should have used more.
So what is your advice?
