I reviewed your last few posts and there seemed to be a common theme - inconsistency. If your CYA test is correct (50), we know the appropriate SLAM FC level is "20", but its not been there consistently. This will most certainly cause the SLAM to drag on and on.
This thread is getting quite long, so it's difficult to go back and review everything from Post #1, so I will recap a few things and hope it helps you get through this:
- Be sure of that CYA. If it's 50, that's fine, but make sure it's not actually higher or closer to 60.
- Maintain that proper FC level (20)
- There should be nothing in the pool except for perhaps lights right? You have a FG pool, so I assume the steps are molded into the shell shape? Your lights are the smaller 3.5" LED perhaps? Of do you have a large size light of some type?
- Liquid chlorine is the primary chemical. Don't bother with any other products. Chlorine is always an effective sanitizer and will neutralize algae as long as the proper (elevated) FC level is maintained.
- When was the last time (if ever) you performed an Overnight Chlorine Loss Test?
Maybe share a pic or two of the water?

I'll start a new thread after this.
Pool water is beautiful. Not even much of anything to clean/vacuum other than normal daily brushing.
FC right now is 16, I added recommended amt of liquid chlorine. There are pictures in my album that I took today - their titles are just the date.
To answer some of your questions there is absolutely nothing in my pool. As you said the steps are molded, and with regard to the lights they are just the normal 3.5" small lights that were built into the pool.
I haven't done the overnight test in a while, I wasn't sure that was something I needed to continue doing because one of the mods had told me to just do the FC test at this point I can do it tonight for sure. As far as cya and everything else I haven't really done any of those tests because like I said I was under the impression to just test FC.
I'll go ahead and do a cya test and record the results and let you know in a new thread. So I guess, if you will, just keep an eye out for a new thread under my username.
Let me know if you think I should go ahead and do any have the other tests.
As always I greatly appreciate your help.

Don't start a new thread - keep everything here.
Retest CYA and report it here.
If the reading falls between the lines, round up to the next larger number (51-59 is reported as 60).
Don't stare to see the dot, just glance.
Be consistent.

Thanks for your comment about not staring at the dot. I had to stare at it almost every test I've done, it seemed like it would never go away. All those tests were before slam. I'll make sure to just glance at it this time. Getting ready to test so I'll report soon
FC 14.5
CYA 30
Added 84 oz liquid chlorine as directed. Curious to hear your thoughts.

Next CYA test...
Really no need to make the test more difficult than it needs to be.
Not a big deal if you pick a slightly higher number for your CYA (say 50 rather than 40) - just don't settle on a number lower than your actual CYA (say 30 rather than 40).
If you run your FC on the high side of target (or even a few points higher) for your CYA it will provide a bit more wiggle room. FC/CYA Levels
- Prepare the sample, mix, let it sit for about 30 seconds
- Take the sample and view tube outside into the sunlight, turn your back to the sun
- Mix the sample again
- Fill view tube to a line - say 60 or whatever you think is a number higher than your CYA
- Hold view tube with only two fingers, near the top of the tube
- Lower tube to waist level - tube in your shadow
- GLANCE into the tube from the top - look away, GLANCE again
- See the dot - fill tube to the next line
- Repeat steps 4 - 8 until the dot is no longer visible with a GLANCE
- If dot was visible at 40 and not visible at 30, you CYA is 40 (dot disappeared somewhere between 40 and 30)

SLAM Process FC level for CYA 30 is 12.
If your FC was 14.5 (2.5 above SLAM level), why dis you add an additional 84 oz?
14 days ago her logs reflect 50 cya.
Ensure you are testing properly, that’s a 20 ppm difference.
There is a thread somewhere when I first started slam that told me my slam level for FC was supposed to be 20. I would have not just chosen that number because I don't know anything about it. So that's what I've been going by. I'll see if I can find the thread and forward it to you
This is what I was talking about. So my initial FC was supposed to be 20 according to the chart and what I was told. And then I was told only to test FC and not just anything else. So I'm a little confused now should I have been testing c y a all along and adjusting the FC to ever match the cya result? I haven't been doing that- because like I said I thought I was only to test the FC and get it to the slam level which I thought it was 20. Maybe you can clarify for me?
Here is the message text...
I took a look at the test again, the FC test. And I have been doing it all wrong. I completely misunderstood what I was supposed to do. So I was using the initial free chlorine Target for every test instead of letting it tell maybe appropriate amount for the cya level. I think I understand it now. I guess we'll just start the whole process again after we get the overnight test results and maybe I'll do it right this time
Just to make sure I don't screw something up, pool math is telling me that my slam FC level should be 12 so obviously don't add chlorine at this point. Is that correct?

That was for when you stated your CYA was 50. SLAM Process FC is 20 for CYA of 50.
In post #186 you stated your CYA is now 30. SLAM Process FC is 12 for CYA of 30.

So, what IS your ACTUAL CYA right now - 50 or 30?
Did your testing method change between the CYA 50 test and the CYA 30 test?
If your CYA is 30, SLAM Process FC is 12.
Hello. At 4:00 a.m. this morning TC was 15. CYA 30.That was for when you stated your CYA was 50. SLAM Process FC is 20 for CYA of 50.
In post #186 you stated your CYA is now 30. SLAM Process FC is 12 for CYA of 30.

And to answer the question about whether or not I was performing the tests exactly the same way each time the answer is yes, I'm extremely careful about that.
Let me know your thoughts.
Thanks.
Also, since I have discovered by mistake and I am now looking at the test correctly, it does appear that my target FC should be 12 so I don't believe there's any action for me to take at this point. Please correct me if I am mistaken.
