Trying to get things right

[KULRN]

I've had my pool for 4 years now. Was too intimidated by the TF test kit in the past, but after using Poolrx for the last year, I noticed bright blue staining to my white plaster. Took sample to Leslie's 7/2/22, Had .3ppm copper. Added CuLator to skimmer. Now with new replaceement TF100 agents, I'm trying to get things right. Removed all the pucks from my feeder as my CYA read 111 that day and started with liquid 12% chlorine. Here are my test results early this morning. pool temp 90
FC 1
PH 8.2 (or higher?)
TA160
CH 475
CYA 70
TC 1.5
Added 96oz 20% Muriac acid (math said 83oz 29%) 96oz 12% liquid pool bleach
At 11am, I did a retest:
FC 0
PH 7.2
TA 130
CH 450
CYA 60-70 (been reading tips to get a better reading)
could not get a TC as my water never got pink... Is it possible to have chlorine get worse after adding all that? I just threw in the last 17oz of bleach I had at this point, getting more today. Tips on where to go from here? Keep adding chlorine on the daily? Best copper stain remover? FYI my pool water has been clear and blue this whole time...

For reference sake it looks like a half gallon (64 oz) of 12% chlorine should increase your FC by 5 ppm. But you're going to need much more. The water looks clear (for now), but I suspect you have a very heavy organic load tearing up that chlorine. If you consider your CYA as 70, the SLAM FC level is 28 per the FC/CYA Levels. I would add 3 gallons as soon as you can and mix really well to get it everywhere. Then re-test in about an hour to see what the FC did and continue to maintain the FC of 28 until you pass all 3 SLAM criteria. Don't worry about anything else but the FC right now.

Best copper stain remover?

Sadly, the only one is very intensive and requires the pool be drained once the stain is mostly lifted. Be sure you want to attack it.

Thank you. I'm picking up 6 gallons today, and I will add 3 gallons and update. I was going on regular fc/cya chart and not the slam...

Not ready for that right now! Thank you. Is it worth getting some jack's magic or similar? Or is that just another can of worms?

Depends on the level of copper. But since you are doing a SLAM Process now for algae, don't add any until after the SLAM.

I'm getting ready to test after adding 3 gallons, but question on overnight chlorine test, I can get a sample after dark tonight and test, and can collect a sample before sun up, but can I test that sample after work? Or does it need to be right away?

.5 CC is good right? Do I still need the overnight test too?

It needs to be done right away. The results can change over time.

Looks like you failed the Overnight Chlorine Loss Test. A SLAM Process would be advised. Do you have any questions about the SLAM Process?

Yes, it's hard to get it right when I'm gone from 6a to almost 6p. Is it better to just try to slam it on a weekend?

Yes, I'm getting lots of practice! The CYA is a challenge, but I got the standard bottle to practice.
