I am currently slamming the pool because I have been neglecting it since school started and developed algae in the bottom and sides of the pool. It is looking much better now. I joined TFP at the beginning of this season so following the methods here for 5 months now. (My husband always maintained the pool until last year) I have some old scale that developed on the liner probably 3 years ago before I realized the importance of monitoring the pH and chlorine levels while the CYA was way too high. I have not figured out the CSI stuff but I know that I need to especially in light of the scale issue
Good news- I have gotten comfortable adding Muratic acid liquid to the pool; I was super nervous about using the stuff and in general probably let the pH get too high because I didn't want to handle it.
PH-7.3 (tested and adjusted from 8.2 prior to start of slam-that was not a long term thing as I have been testing and adjusting all summer)
Borates-less than 30 but more than 15-maybe 23?
I have done some reading on here of old threads about scale. It seems very likely to be calcium scale. Are my other numbers okay to lower the pH to 7.2 and keep it there while brushing frequently over time the thing to do?
