I hope you can answer a question for me. I just had my pool re-plastered last week. I went to pool store and had them test the water to see what I needed to ad. They said I needed 3 pts of muratic acid. But for some reason the young man at the store sold me 4 gallons of the muratic acid. I didn't pay too much attention because I was buying a bunch of stuff at the same time. When my friend and I got home I said to him "Why did the guy sell us so much muratic acid, we only needed 3 pints?" He didn't pay too much attention to me, just carried the crate out to the back, He then poured in 1 of the gallon containers. I came out to tell him to stop, but it was too late - he had poured the whole gallon in.
I siad not to put anymore in because we already had too much, I would take the rest back to the store. Two days later he poured in another gallon of the muratic acid. We now had 2 gallons in the newly plastered pool instead of the 3 pints. This time I made sure he listened to me. I took some of the water back to the pool store to be tested and they told me to add 14 lbs of a white powdery substance, which I have done.
I am hoping and praying that that large amount of muratic acid didn't damage the new plaster on the pool. Please tell me the truth. It was supposed to be a "Black bottom" pool, but now looks very mottled. Is that from the acid or is that what happens naturally? I just hope the new plaster wasn't damaged. Can you please tell me the truth, good news or not.
Thanks for your help.
