We set up and filled last week and knowing nothing added one gallon of 12.5% sodium hypochlorite to help us clean the pool liner as it filled since we purchased it used and it sat for a year before we set it up. It had a lot of stains on the liner that are now gone. We added another gallon the day after it was completely filled noticing a reddish brown silt on the bottom of the pool that quickly turns the pool water rust colored when agitated. I can't get that to go away. < that is one of my needs
>Next need is that I can't seem to get the total alkalinity down. I have added a gallon of muriatic acid in increments of 6 cups at a time every 2 hours and brought it down from 240 to 180 but it was right back up again today when I tested.
Here are my readings:
TH - 250
TC - 0
TB - 0
FC - 0
pH - 7.2
TA - 240
CYA - 40
We are trying to use the BBB method and would like to stick to it if at all possible.
