Thanks, I didn't know that!Pick a spot far from any returnns... consider where you think the lowest amount of chlorine would be? That's a good testing site.

So frustrated with SLAM

This is awesome, thanks so much!View attachment 326667
P-o-P. Pool owner patience. Resist the urge to overreact and over correct.Stay the course. You’re doin AWESOME
I am going to test everything again tonight and will post the results here.
That is very encouraging! We have had similar fights.
OMG <fans self wildly> Nooooooo... they're *hardly* "experts" !!
For those who are still with me and wondering, here are the latest tests:
FC: 21.5
CC: 0.5 (had been maintaining at 0 earlier in the SLAM)
Calcium hardness: 300
Total alkalinity: 100
CYA: 50
PH: over 8.2 but is this accurate with chlorine this high? We got it down to the recommended range before starting the SLAM.

It is a false high reading which is why you lowered it before you started. It buys you a week or two during the SLAM when you can't get a reliable PH test. (Anything over 10 FC)
It turns out my husband kept the box of what was put in the pool during closing. It was an Ameripool pool winterizing kit which contained a gallon of On Guard winter protect algaecide and a quart of On Guard stain and scale preventer.

You can add a drop of R-0007 to neutralize the chlorine, I have read in older posts that very high chlorine can indeed interfere with the CYA-test.
Most important thing with the still very cold water is to let the sample warm up to room temperature before doing the CYA-test.
Could you post a photo of those two winterizing products?
Is your SWG off during the overnight period?
Is your SWG off during the overnight period?
Yes, we haven't turned on the SWG yet this year. We are just using chlorine. Here is a picture. Appreciate your help!
Thanks. I didn't realize I needed to let the water warm up for the CYA test. I will try again with warmer water.
Yes, he put it in the pool. I don't see copper on the label but I'm really not sure what was in it. Ugh.Did he put that stuff in the pool? Does that algaecide contain Copper??

No, copper is sometimes listed only in the ingredient block or as "trade secrets" in which case we've looked at the SDS online and seen it.

That's a lot of copper. You will want to take a water sample to the pool store and let them test for copper to see how much is in the water. Too much copper will cause stains on the plaster, and will turn light colored hair and fabrics green. Don't let the pool store sell you anything.
Oh my. Thank you, we will get it tested. So if we have too much, we need to drain some of the water and refill?
Yes, unfortunately that's the only way to get rid of metals. You could go the sequestrant route, but honestly since the only way copper gets in the water is if someone puts it there, its better to drain and replace water. Once you use sequestrants you have to add them regularly as chlorine breaks them down over time.
Thank you. That is unfortunate and annoying but we'll take care of it!
My husband ran a sample to the pool store and they tested and said there was no copper. However, they don't know if their test measures total copper or free copper. So are we good or do we need to find a store that can definitely measure total copper?
