Ok, guys. New pool owner here and I made a big mistake. 18,200 gallons and put in last summer. Gunite w/ plaster. I live in South Louisiana w/ very soft water.
Last winter, my pool developed bleach spots or calcium deposits of some sort. The pool contractor came and drained, sanded and refilled the pool. No charge. However, they didn't put any chemicals back in it so I tried to do it my self. I screwed up b/c I used test strips until the TF test kit came in. Bad idea. Well, when the kit came in and I tested it, I way way overshot some chemical usage due to the test strips. At any rate, the pool calculator says to drain my pool some 42% of water and refill. Do I really need to do this or will it self correct in a couple of weeks. Is it ok for my girls to go swimming in?
Here are the results: FC = 9, Combined Chlorine = 1, pH = 7.5, CH = 520, CYA = 110 and alkylanity = 110. I tested it 2 days ago and the numbers have moved an inch. I did all the chemical adding on Sunday/Monday so its been about 5 days since my screwup.
Any help would be appreciated.
