I am helping my 84 YO FIL open his pool. As usual it's a green swamp but by using the SLAM process, we can typically get it clean in a week or two. Took cover off Thursday night, started pump and took some readings.
TC=0
CYA = 30
pH = 8.2+ (over the chart)
TA = 40
ch = 120
So, I asked him not to start slam until we get pH down as my understanding is the SLAM will be more effective with a lower pH. Unfortunately, he went ahead and added all his bleach anyways (sometimes he just doesn't understand/listen - old age). So now there is no way for me to get an accurate pH reading as the SLAM has begun.
My question is, can I add Muriatic acid during the SLAM process? I know the pH was at least 8.2 before the SLAM started. According to the pool calculator, I should add 46oz to go from 8.2 to 7.2. I know the pH could be higher than 8.2 but I assume adding the muriatic acid should help, right? Then we could finish the balancing once the TC/FC levels are back to normal.
