Thanks for the additional information. My plan actually was to lower the CYA to around 50, but for now it seems I need to just hold off for now until we are through the worst of the summer. How do you determine what the best CYA level is for the pool. With a higher CYA I need to maintain a...

Thanks for the confirmation about the chlorine use. My CYA has been holding steady between 60 and 70 (sometimes difficult to read with old eyes) so I have not tried to increase it. I'll just keep an eye on it to ensure I don't suddenly start losing CYA. Just a question regarding CYA. If the...

I started using the TFPC methodology in September 2016 and has been very happy with the results. Since I started following the methodology after the summer, I wasn't sure how things would change during the summer time. Starting Sep/Oct 2016 I was using around 12oz of 10% daily on average. This...

I am also in Phoenix and my numbers are very similar to yours. For now I have closed my aerator, but the pH still creeps up. I will do a full test this weekend and see where I am, but the last time pH was 8.0 or just below, with 2 drops putting me in the 7.6 range. I added 24oz of 31.45% MA. My...

Following are the test results from Friday: FC: 6 And Saturday: FC: 6 CC: .5 pH: 7.8 TA: 90 The FC is very predictable now and it seems 16oz of 8.25% is about what is being consumed at this time. pH is another issue. The pH went up again with the TA now at 90. I was hoping the pH would...

We had a cooler day today with a few drops of rain. Tested the water tonight and it looks like I have nothing to add tonight: FC: 8 pH: 7.4 The FC:8 is probably not a full 8 since the last drop change the color from a hint of red to clear. But at 8 I am not adding any bleach. The pH of 7.4 is...

The numbers are in for the day and it is basically the same as yesterday. So I decided to check the TA also: FC: 7.0 pH: 7.6 TA: 100-110 The TA must be very close to 100, but I think there was a slight change in red when I added the 11th drop. Either way it is coming down nicely. The pH also...

I decided to add some bleach last night and added my normal 16oz of 8.25%. Today the FC number stayed with the trend, which means tonight will be another 16oz: FC: 7.0 CC: 0.5 pH: 7.6 The pH was down a bit, so I decide to add another 12oz of MA. By Thursday or Friday I will evaluate the TA...

Thanks for the information. I have never monitored the pH this close so I'm not sure when pH does not rise that fast. Once I get to adding MA once a month, is that a good indication, or maybe even less frequent.

The numbers are in for the day with TA showing a trend downwards: FC: 7.0 CC: 0 pH: 7.8 TA: 120 I added another 24oz of 29% muriatic acid to bring the pH down, and it seems at this rate my TA will be down to around 90 by Thursday. I have not added any bleach yet, but I am thinking of maybe...

Thanks for the information. I probably did not understand that the higher TA will let the pH rise quicker. What will be a good target level for TA? The recommended level for TA is : I've never been sure what the 90+ meant. Does it mean it is ok to be over 90, but it is recommended to be...

I tested the water again today, and for some reason my pH is higher again. The aerator has been closed for a while now, so I'm not sure why the pH went up again. Following are the test results: FC: 7 CC: .5 pH: 7.9 TA: 130 Since the pH is an issue again I decided to go with 24oz of 29%...

Thanks for checking on me. I thought everybody was getting tired of my "no change" posts so I decided to scale down my posts. The last two day my tests have shown that I am definitely getting to the point where I can maybe test the water every second day. My test results: 9/16/16: FC: 6.5 A...

I did not check the water temperature, but I will check it when I turn the aerator on again to see by how much the pH increase. Did another test with a few additional data points: FC: 7 CC: .5 pH: 7.6 TA: 120 Looks like I can bring the TA down a bit more, but I'll wait for after I ran the...

Did the test tonight after another 24 hours and without the aerator running, and saw some improvement to the pH. At least now I can see that I at or below 7.8, which makes it easier to read. I did not test the TA yet, but decided to go with another treatment of muriatic acid to get the pH to...
