Questions about levels, why I am getting skewed results, and quick thoughts, advice while I wait to receive one of your test kits

CC or FC?

Or did you mean CC was 0.2?
Yes
How to make an unexpected trip out of town yesterday so I couldn't test. Tested this morning will actually right now
FC is 6
CC is 0
CYA is 30
Pool Math says my target cya is 75 and recommends that I add 78 oz of dry stabilizer.
is that what I should be doing?

Should I test for anything else?
 
I went ahead and did Total alkalinity just to see what it was. It was at 115.
The instructions it for that level is to reduce pH to between 7.0 and 7.2 with acid and then aerate to increase pH.

In a situation like this I expect there is a certain order of things with regards to what action you perform. Am I right with that? And I mean that as far as generally speaking.
To be specific as to the readings that I have today, what is the recommendation going forward?
 
Sorry, I spoke too soon. I went back and looked at pool math with the revised levels, after I added the TA, and I see it has given me new instructions. Sorry I jumped ahead without checking Cool Math pH. If you haven't put it together yet, I'm totally ADHD and I sometimes get ahead of myself, so sorry for the missteps sometimes.
 
Sorry, one more question. The recommendation is to add pH down or dry acid when I looked at the list it gave the note that PH down could sometimes be harmful for swg pools. So I am assuming that muriatic acid is the way I should go. Correct me if I'm wrong.
 
Where exactly did you see your target CYA is 75?
CYA 60 or 70 would be fine to start. Easy to bump it up 10 ppm if needed.
And the CYA test always gets rounded up to the next higher number. IfCYA is 61-69, round up to 70.

How did you measure a TA of 115?
25ml sample, each drop is 10. Result is a multiple of 10.

No dry acid - especially with a SWG. Muriatic acid only.

Hi, I'm back. Had to make a quick trip out of the country for business reasons. To answer the last question, I am a little confused. All I did was do the tests as directed and fill in the amounts. It's what I've always done in the past and a lot of times I get questioned about why I've done something so I'm kinda at a loss.
I cleaned, backwashed, etc. today.
I did the FC, TC, ALK & PH.
I've logged corresponding values. When I look at pool math and I select anyone of the values it tells me instructions to correct what that level is showing, at least that's how it looks to me. My question is where do you see an overall view where all tests are taken into account and then you are given instructions based on the comprehensive data available. Do you just do each correction on its own and if you do that what order do you do them in? I think this is where I get confused.. I'm just not sure what to correct and in what order or I don't know- some direction would be appreciated.

This is where time and experience comes into play. While the app is a great tool, it doesn't know all of your pool or local details. For example, it may tell you to have a CYA of 50 (summer), but if you live in Phoenix with 155 degree heat, your CYA may need to be higher. It was for me down here in Texas. IT may say a TA of 80 is fine, but you have learned that a TA of 60 is better because it keep the pH from rising so fast. If the app is saying to increase CH, but you are already at 250 and concerned it may not be needed, let us know and we'll confirm.

Those are just a couple small examples, and there are others. It just depends. This is why posting questions here is a good idea to help give you clarity about app results.
 
Ok - i just posted a whole round of test results from this morning. When I select each one - they each have their own recommendations. This is where I get confused, I don't know if I should do each recommendation starting from the top or how that even works. If you could look at my log and try to interpret it for me so I have some idea what to do when different things are out of whack at the same time I would appreciate it. I will wait for a response before I do anything. Just a note, it has rained every day for the past week and has been cloudy.
 
I looked at the recommendations for cya. It gave me a correct recommendation number, however when I selected liquid stabilizer instead of a dry it did not give me an option to choose what percentage of muriatic acid. Sending a screenshot of what I see. Any information for me on why it would not give me the option to select the muriatic acid percentage?1000020448.jpg

Additionally, is cya the next thing I try to correct when FC and TC are within normal limits. That's part of the question I asked before regarding what Corrections need to be taken when multiple things show out of range.
 
They are different chemicals.
Stabilizer increases CYA.
Muriatic Acid reduces pH.
Completely get that and Understand. What it comes down to I guess is if you look at my log there are multiple things out of range. I don't know what action to take at this point. That is what I am 100% having problems with. If multiple things are out of range, and I'm sorry if what I wrote is not exactly accurate I might have gotten my terms mixe up but you can see it correctly in the log.. I need to know what to correct first in a situation where like I said multiple things are out of range.
That's what I have been trying to ask for the last few posts. I understand the tests, I understand the recommended levels, and I understand what each correction is directing me to do. But I don't know overall what I should start with as far as making corrections.
 
In your last log, you did not include pH. I think you logged your CYA as salt.

Everything else looks ok, except pH. If your pH is still above 8, I would lower your pH to 7.6-7.8. Use muriatic acid.

That's probably what happened, sometimes it's hard to see what space I'm actually entering in especially if I'm outside. Yes, I know, go inside and do it. I will do that from now on to make sure. Thank you for taking a look at things. Yes my pH is high it's 8.2. When I went to the recommendations and chose the liquid instead of the dry, it used to give me a choice as to what percentage muriatic acid I would add, and it did not do that this time. So I haven't added anything because I don't want to add in an accurate amount. That's the screenshot I sent. I'll try it again maybe it was just a glitch.
 
Well it did give me a choice this time but I ran into a strange thing I bought normal muriatic acid and when I looked at the information it said it was 20% however that's not an option I am going to send you a picture of the front of the bottle in case you've ever used this before maybe you can direct me as to Which percentage I should choose. Do I choose 28 and then just do a little bit less or what?
