Well I read that your pH levels are not reliable during the slam process, so it seems as though I'm on my way to that from the two gallons of bleach I've added over the two days, so it was just wondering if it is reliable. My pH yesterday was yesterday 7.6

When your filter pressure rises by 25% over clean pressure, clean the cartridges.

Yes...SWG needs to be off now.
You need to keep it at 20 until all the conditions of the SLAM are met. I first would look for Clear water and see if it passes OCLT.
I made this assumption that there were two readings that matched up...it was high and needed correcting. I should have stated that.
Okay last question for now... I shouldn't start this till tomorrow morning? Or can I go ahead and add more bleach now

No time like the present. I would get going now, it can take some time to fix...so the sooner the better. Just remember that as your chlorine is killing algae your brushing and vacuuming will be sending it to the filter...so try to keep it clean and the water should start to clear up too.
Ok I added muriatic acid and bleach I scrubbed and vaccuumed. I then retested.

Am I supposed to keep checking CYA and pH during this process?

Nope. Just FC. No need to do the CC either. Wait to do CC when you do the OCLT to check for completion.
This morning I've tested twice, vacuumed, cleaned cartridge (dirty), and cleaned all the filter baskets. Below are my test results from this morning prior to vacuuming and cleaning the filter.
I do have a question... The cartridge filter was pretty dirty, but my pressure had only gone up by one or one and a half PSI. I wonder why the pressure isn't increasing if the filter was dirty? Is it because it was filled with lots of sand maybe and the water was able to pass through freely? I will certainly start cleaning up more frequently now.
I plan to vacuum at least one more time today, or is that overkill? I think it's all started with the sin and mud in the bottom of the pool so I'm trying to get all that out and I get a little bit each time but nothing compared to when it first started.

Ha ha. And I'm sure those number above were from FC and not CC right?

Vacuum once a day should be fine unless you see additional opportunities to suck-up that sand and junk that may have settled on the bottom. In that case vacuum. I always rinse of my filter carts after a vacuum as well.
One more question, my CYP was 50 when I first started. I tested it two more times since the first testing just to make sure I'm doing it right and both of those times I got 42. I initially shocked the pool with the CYP of 50, but now that I'm getting the reading of 42, should I adjust my slam FC number to 17? It was at 20.
1145 test of FC was 19.5
Thanks as always

For now, let's stick with your first number (50) since you validated it twice. The recent test may have just been an odd one. But if you get close to 40 on the next test, then you can adjust the FC. FC of 16 for a CYA of 40 or FC of 20 for a CYA of 50. No need to split the differences.
Sorry if my note wasn't clear. I got 50 one time, the first time I did it. I got @42 on the subsequent 2.

Oh, in that case I would just keep the FC at 16 and brush, inspect, repeat. Fun, fun, fun.
Lol ok I'll let it drop to there. Thanks!
I'm going through that reagent quickly. Where do you get yours?
