Chlorine FC 10 to zero in 2.5 days (w/ Pics)

Good job! For the CYA, dangle that sock in front of that return and after 30 mins, start squeezing.

It can take 24-48 hours to fully register in your tests, so I wouldn’t add anymore until you’re sure it’s stable and less than 30-60.

CYA addition. If you are adding it through the skimmer, it is normal for the pressure to increase temporarily. Backwashing too soon will only dump it!
FYI, even with the sock method, mine took over a week to dissolve 2 lbs.

I believe it was said earlier she was “off to find socks”, so I assume sock method and dangling them in front of multiple returns. But that’s very valid! If you do add through skimmer, don’t backwash for a while. Can take considerably longer to mix through. Sock method is preferred, but as you noted it can be a bit to register the full increase.

Plot twist : Socks is her cat that is taking longer than usual to come home.

Hey y’all!! I got more pics below of CYA tests from today! Okay so slight recap, I used 4 socks to dissolve all CYA yesterday (6/16) afternoon and added 1 gallon LC. No backwashing has occurred. My filter runs 24/7.

6/16 midnight - FC 2.5
6/17 8am - FC 2, CYA 30
6/17 8am - added 1 gallon of LC
6/17 3pm - FC 5.5, CYA 30

I think the CYA read the same outside but I couldn’t get good pics.

Also, good news my uncle is gonna help me next weekend replace the sand in the filter, so I’ll get my hands on some sand.

It is 90 degrees and sunny so I plan to swim but I will keep testing each night and morning. I won’t be SLAM’ing until Monday morning.

Thanks for all the feedback everyone! Thoughts welcome!

I’d say as of right now, based on those pics, your CYA is 40. Wait until tomorrow afternoon to test CYA again. Save some solution. Tomorrow afternoon will be 48 hours of mixing. Good job!

From those pictures, CYA is 30ppm.

From those pictures, CYA is 30ppm.

I am terrible today. I saw 30 too, but apparently typed 40. Thanks for the catch!

You likely don’t need to replace the sand unless it’s all caked up with junk. Try just deep cleaning it like mentioned earlier and keep adding chlorine in the water.

Ohhh okay, thank you. I just searched that as well, I will try deep cleaning first. Thank you!

My personal opinion is that if the water is cloudy - I’d SLAM. I’d also personally be more inclined to test OCLT using SLAM levels than normal levels since a 0.5ppm loss is a larger percentage of normal chlorine levels than it is at SLAM.

I will also say that an SWG is the best decision I ever made for the pool. Keeping consistent levels is so much simpler now.

It’s easier to clean the surface junk when the sand has dried out - but it can be done either way. Check where the sand level is expected to be. Mine wasn’t right, I had about half the sand level expected when I opened it for the first time. Adding 100lbs of sand has helped I think. Certainly my water is crystal clear.
