How was your stabilizer in the chemical test. If it is way too high,
draining off some water is the only real answer.

My understanding of excessive stabilizer is that it
reduces the effectiveness of the chlorine, not that
it stops the chlorine from showing up. *Meaning that
with too much stabilizer the proper level of chlorine
will still show on the test, it's just that it won't be
working like it should.

One thing I recommend is a Taylor test kit that
will test for all the necessary chemistry, including
stabilizer. *They last several seasons and for
$50 or so it's well worth it

You have plenty of chlorine on the 2 bottle tester but the pool store
can also test for "free" chlorine that is not locked up by the
stabilizer.

Kurt indicated he was not seeing any chlorine, free or total. You
don't need the pool store to test for free
either. That can be done with a Taylor test kit, which,
IMO pool owners should have.



I had it once and draining about 2 feet of water from the
pool was the only fix.
I backed off the tabs

Again, I agree that you can have problems where
free chlorine is not showing up. But it's my understanding
that excess stabilizer does not actually effect the
level of free or total chlorine or make either not
show up. My understanding is that free chlorine is
there, but CYA forms a weak bond to it and
hence inhibits it from working. Too much CYA and
you have chlorine it's just not as effective. Kind of
like the higher the PH the less effective chlorine
becomes. It's still there, measurable, just not as
effective as a sanitizer.



I use and make up any deficiency with liquid but
usually it is not necessary. I always shock with liquid. (a 2.5 gallon
jug once a week in the summer).
I cut the chlorine by a third in the winter.
Other than that I only use a little acid to keep the pH right.
I am about 4-5 years without any chemical wars.- Hide quoted text -
