Well I see CYA lowers ph a bit too. So that'll be the first thing. Then I'll hit with acid and fix ta after the slam since ph goes crazy during slamming.
I guess that will work...

If you want to adjust the TA first just go ahead and add some (130? oz) baking soda and then do the pH and SLAM. The muriatic acid itself shouldn't affect the TA that much.
So I've got everything hooked up and put stabilizer in a skimmer sock and I'm trying to adjust TA and PH. PH looks to be off the roof 8.2+. Based on test results I put in 127oz baking soda to increase TA to around 70 and put in 17oz muriatic acid to lower ph to around 7.2ish. After waiting an hour, I see no change in either.... Any suggestions?
Update: I'll increase muriatic acid to 32oz. I didn't calculate for the increase of TA to 70. Just tested the water again and it's at 70 TA now.

You only need to give it 30 minutes to mix. When it's reading up in the eights it could be 8.2 or 8.7, 9.2 ... You treat it for the 8.2 and hope it comes down but if not it's just that high so you do it again until it comes down into the 7's where you can actually read it.
What is the FC level now? If it's above 10, your pH will read falsely high.

This is before slam. I finally got PH back down to 7.2. TA settled at around 60. It ended up taking 3 doses of 26oz muriatic acid.
Okay, so an update: After the first half hour, I only lost .5 FC. I was a bit high at 12.5 FC for my shock so it only lowered it to 12. I left it for another 30 mins and checked, FC was at 11. I added 20oz bleach to raise back up to 12. After another hour, the FC is still 12 and CC is 1. It's killing off stuff but it doesnt seem to be consuming FC that fast. The water is a cloudy grey which is good. Visibility is only 2-3 inches with a flash light. It's dark outside 
I guess I'll continue this until I goto sleep and recheck in the morning before work. I just hope it doesn't get to outta control being gone for 10 hours since the stabilizer hasn't totally dissolved yet.

Now is the time when it seems to slow down. This is the time to take a picture of your steps/stairs so you can see it get clearer bit by bit.

So it looks a bit better this morning. The FC tested at 10 after 7 hours, so I raised it back to 12.
The CYA stabilizer is almost dissolved already. Is it normal to dissolve that fast? I thought it would take a week.
I got some wall cleaning to do above the waterline, but that will have to wait until tonight.

The granules dissolve fairly quickly, but for some reason, the test results read low for a few more days, so wait to test. From past threads, I will tell you that behind those steps is a really common hideout for algae. I'd bet on it.
I do too. I have them pushed a bit from the edge so I can hopefully brush back there. I hate them tbh. They are not solid so algae will cling under the steps too which are impossible to reach. The only way is to remove them which is difficult as well because they are anchored with sealed milkjugs of sand/cement.
So how long does this usually take. I'm about through 8 gallons of bleach, raked out the bottom, brushed the walls and yet the water is still very cloudy. Visibility is only 3 inches.
With 8 gallons you are just starting.
Every pool is different. It depends on:
-how often you are able to have the water at SLAM level?
-how often are you brushing the pool?
-Have you been running the pump 24/7?
-is your bleach fresh?
-just how bad was your pool?
Some pools clear up in a week. Some take weekS. It all depends on the conditions.
I wish I could give you a better time line.
Keep it up and it will clear up. Take a pic of your steps each day. You will be able to see the progress that way. Each day should be a little clearer if you are on top of the SLAM. Of course brushing will "cloudy" it back up but it is helpful to filter the stuff out.

Hello again everyone!
So it's been a little over a month long and the water is clear to the eye. However, I am still having to add a gallon of bleach everyday. I've noticed there isn't a huge change within an hour or 3 hours, so just leaving it alone for 24 hours, FC goes from 12 to 5. I am going to do a overnight test tonight (if I remember to test in the morning), but could the sun alone consume 7 FC? My CYA is 40 but the pool is in direct hot TN sunlight from 6am to 8pm everyday. Water temp is almost 80.

Alright, well I remembered to do it once I woke up and here we go.
8pm = FC 12.5 (25 drops)
12am = FC 12.5
7:50am = FC 12.5
So... I guess I'm done. So my question still lies with what to do about the sun consuming 6 FC everyday. How much CYA do I need to increase it to?

I see the OCLT and the water sure looks clear. CC is still .5 or less?
50 is a respectable target for CYA. Anywhere from 40-50 should be acceptable. Leave yourself a little breathing room so you can use pucks in a floater if you want to leave town for a few days this summer.
