We have an in-ground pool of about 50,000L in Alberta Canada. This past winter the cover we used failed in several places and the water underneath was horribly dirty.
We added excess liquid chlorine like we do every spring, let it sit a week and found chlorine was basically gone.
We tried again, and followed the instructions from our local pool shop but after 3+ weeks of several super chlorinations, non-chlorine shock, pool perfect etc the water is a milky white and isn’t getting better.
the stuff they told us to add to the pool also reduced the Ph lower than we were comfortable with (while alkinity was high.) and so we decided to drain back to winter levels and fill it up with clean water.
instead of following the pool store’s instructions, and add a bunch of junk into the water again, we bought this app and I’ve been doing some reading on TFP forums.
I’m hoping you might have advice for us to get our pool water cleared up so we can start using it.
it isn’t green algae, but still milky. (Photos are from before the draining was done)
Thank you for your help!
below are my logs. Note that we bought the app part-way through this process so not everything is logged, but I’ve tried to make it as accurate as possible.
