Hello all,
I’ve got a question regarding keeping my pH down in the proper range.
I have a fairly new (completed in December 2006) gunite/white plaster
inground pool, which is approximately 12,000 gallons. Currently the
TA is around 90. What I’ve noticed is that I’m adding muriatic acid
every week to the pool to keep it in the 7.4 - 7.6 range. I do add
some tap water each week to keep it at the proper level, and our tap
water pH is pretty high (probably at least 8.2 - 8.4). It seems to me
that I shouldn’t be having to add a pint or so of acid every week to
keep the pH where I want, but perhaps this is perfectly normal. Does
the pH keep rising on me because of the relatively new plaster? I
wouldn’t think the amount of tap water I’m adding would cause a need
to add acid every several days to keep the pH down, but perhaps that’s
the whole issue. Thoughts?
Thanks,
Greg

Thanks for the replies. No, I do not own a salt pool, but the pool is
new and I’m suspecting that the pH wants to creep up because our
plaster may not be completely cured. I have been told that it can take
quite a while for complete curing even though it’s perfectly ready for
pool use. I’m only adding a quart of muriatic acid a week, so it’s not
too big of a deal.
