Water testing and left over trichlo

[PoolDoc]

Keep in mind what your goals are:

1. Chlorine levels stable overnight.
2. PH between 7 & 8 all the time; for you with high CH, 7.2 - 7.6 would be good.

3. Once chlorine is stable overnight, you want to maintain FC levels that range between 5 & 10% of your CYA level (225).

Chlorine has stayed stable overnight. Unfortunately, with FC at 11ppm, based on your previous post I may be getting inaccurate pH readings.
I had pool at about 15ppm on FC, but chlorine odor was pretty strong. I figure 11-13 is a decent number with CYA levels where they are.

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?
