Water testing and left over trichlo

[PoolDoc]

There should not be any chlorine odor at 15 ppm UNLESS there's something in the water to still oxidize. As we speak, I have a heavily used 200,000 gallon local country club pool at 15 - 20 ppm FC . . . and the water is completely odorless.

Fair enough, I will continue to monitor.

So, we did some make shift aeration this weekend. Seems as it had a small effect.
Added 2 jugs of bleach after this test was taken.

ok. keep us posted.

Posted new test results.
Added 1/2 gallon muriatic acid to reduce pH levels. According to this post http://www.poolsolutions.com/gd/lowe...p-by-step.html
I am going to lower to 6.8 as this is the lowest my tester will go, I will then begin the aeration to lower the TA.
How long should I wait before the next dose of acid to lower pH?

The aeration raises the pH, not lowers the TA. Don't drop the pH to 6.8 on your kit because by doing so, you don't know if 6.8 means 6.8 or any value lower. Lower it to 6.9 or 7.0 instead. You add the next dose of acid when your pH is raised back up to 7.6 or so.

New results posted, seeing nice results in TA and CYA.
Will continue aeration and add a small amount (1/4 gallon) of acid to lower pH.
