Yesterday morning I was at FC 6.5 pH 7.4, this afternoon FC 4 pH 7.7
So my FC from SLAM has now drifted below target level and I need to start adding chlorine routinely. While also working on lowering TA, do I lower pH first, let it circulate, then add chlorine?

Got my TA down from 200 to 125 this week. Going to stop trying to lower it for a couple days to see the #s and I'm out of acid.
FC 5
pH 7.6
Temp 82
Assuming CH hasn't changed, CSI is 0.5

Good job! My pump is off until tomorrow as I am putting in a skimmer. I have everything apart. Going to get in and vacuum.
I misunderstood the Min and Target FC levels and now I'm guessing I have organics again, as I've been losing 4-6ppm per day. What I think I need to do in the future is calculate my own target, and raise to that FC level so that it won't go below the minimum before the next dose. I was adding just enough to reach the target from the cya chart everyday but starting going under the minimum when the temps got up.
Raised FC to 10.5 last night and OCLT was -1.0ppm (9.5 at dawn). Going to run all my tests again now. Seems like I may need to SLAM again.

No that is is hot I keep my FC around 9 since the AZ sun just eats it up. You only lost1 ppm overnight so techs that is passing. It would not hurt to run SLAM levels for a few days. Just to beon the safe side. The target 3-4 ppm higher than target level for daily adds
Thanks, not sure how I didn't realize that was the idea for a target FC. Here are my 9:20 tests, already lost 1ppm FC since 5am.

My last 24 hours:
5pm FC 2.5 CC 0 Add 1gal 10%
8pm FC 10.5 CC 0 (after sundown)
5am FC 9.5 CC 0 (before sunup)
920am FC 8.5 CC 0
6pm FC 7.5 CC 0
I was surprised to see -1ppm early in the morning and then only -1ppm through the rest of the day as it was 110F. Doesn't make sense to me, but verified the 7.5 twice.
Now I'm debating if I need another SLAM or not. Lost 3ppm over the last 24 hours. Looking back at my log I've dipped below my minimum of 4 almost everyday since June 2.

Thanks for posting up all of your test results and progress. I'll be moving into a house with a pool in a month or so and this helps give me some expectations for what I will be dealing with here in the Phoenix area. subscribed!
If water is clear with no visible signs of algae then there is no need to SLAM. If you see visible algae then I would SLAM.
8am FC 6.5 added 33oz to shoot for 8.5
6pm FC 6 pH 7.6 added 42oz
Water is clear, no algae I believe, just brushing dust/dirt.
