first, thanks for all the info on this topic from the gang @PF.
Finally started fill today. As we discussed, the TA of the well fill H2O is 500.
Is it ok to start the aerating by shooting the fill up into the air and then into the pool now?
the water is not high enough to bring the pumps and filter online. pH is 7.1 in the pool today.
I know it would be a bad idea to add acid when the pH starts to rise because of no circulation.
but, the process has started!!!!!
