I have a 20,000 gal. inground vinyl liner pool. Do I have to worry if my
calcium hardness level is low? Also, I just opened my pool yesterday and along
the crease of the liner(where the wall & bottom meet), I have what looks like some rust stains. I shocked the pool and look like everything else is balanced. Any suggestions what to do?
Thanks,
Dave
