I tried asking this same question in another thread but I think it probably belongs here. Only a chemical guru probably has a shot at this one.
I will be doing an acid start-up on a plaster pool and adding 1 gallon of acid per 2500 gallons of pool water. United Chemical says brushing the pool once a day is sufficient to maintain the acid in suspension. The plaster company thinks the main pump should be running (or sump pumps) to not only mix the acid into the water but also to prevent the acid from coming out of suspension and collecting in the deepest part of the pool.
It just kills me when experts have such varying opinions.
Who is right?
