Hello everyone! Please help with advice. I took a sample of water to Leslie's swimming pool service. They mistakenly put into their computer calculator that my pool had 275,000 gallons instead of 27,500 gallons - gave my son 5 5-gallon buckets of alkilinity up to put in which he did. next day, I discovered the problem and took another sample back to leslie's who have told me i must now add 20 gallons of hydrochloric acid to fix the problem! This sounds dangerous to me but I am not a chemist. They have apologized and are giving me all the chemicals for free but I wonder if it is safe to add so many chemicals to my pool. Would it be better to drain my concrete pool and just put fresh water in? Thank you so much for any advice. Much appreciated.
