Going it alone. Need help.

So pool has gone green again.
TC 5+ on the yellow test.
FC 4
CC 1
PH 8.2 +
The PH seems to be going up all by itself. Why?
So I will use pool math and muriatic acid today to try and get ph to 7.2-7.4
Then shock it.

It is not uncommon for the pH to rise. Lower it and then follow the SLAM process until you pass the 3 criteria to stop.
To be clear, make sure you are following the SLAM process and not just a one time "shock". If you don't follow the process through to the end the green will come back!
Ok thanks that is very helpful. I will check the difference between SLAM and shock!
PH= 8.2 (put in pool math m acid and in an hour it had gone down to 7.2.)
FC= 1
CC= 0.5
TA= 75
CYA 38
So then put in pool math 5.25% chlorine. Tested an hour later and FC was 22, way above the 15 level I was aiming at.
Tested after three hours and the FC is still at 21.
What am I doing wrong?

If FC jumped that high, it means that either a) your pool is not as big as you think or b) the chlorine is stronger than you think. Is 5.25% what they sell where you live? In the US, Chlorox is 8.25%. The difference in strength would account for FC target of 12 or so becoming 21.
it says 5.25% on the bottle and comes from US I think.
What do I do now I have put too much in?

Think I am close with pool volume although evaporation has reduced depth by an inch or so over the last week since I put water into it.

This morning pool looks a lot better. First I scrubbed it then took following readings
PH 8.2+
FC 20
CC 0.5-1 (2 drops)
I have cleaned the filter and put muriatic acid in again to reduce PH and will scrub again and test again this afternoon.
But FC is only a little down which indicates no algae left to eat it?

How can the PH risen so much?

Do not test pH again until you finish SLAM. It will read too high when your FC is high. (above 10 ppm)
Your CC's result indicates you have not finished the SLAM. Are you following the SLAM procedure exactly as it is written in Pool School?

Yes I am trying to follow the SLAM procedure.
Have I made a mistake putting in more m acid?

Guess I forgot about the bit that says PH test is not reliable during SLAMing.

Probably not a bad one at all. Done is done, anyway.
Stay with the SLAM article and do EVERYTHING it says but don't do ANYTHING it doesn't say unless we suggest it.
This morning my pool is crystal clear
FC 15
CC 0.25
Passed OCLT test.
Filter still had green in it when I cleaned it.
Reverting back to normal pump times.

Yesterday at 4pm it was 14.
This morning 15.
So basically no loss overnight.

And in the morning yesterday around 6:30 FC was 20.

I will check again later this afternoon.

Well, yeah, but technically going up is impossible ... unless you have tablets or SWG or something adding chlorine which invalidates the OCLT.
I would do the OCLT again ... and make sure the readings are done with no sunlight.
Also how did you get a CC or 0.25?
It sounds like you are done, just want to be sure.

I think FC 15 this morning v 14 last night is due to reading error.
Re CC of 0.25: at first it looked clear but then I saw a slight red tinge and added one drop. I think half a drop would have worked too.
Just tested at 4:40 pm and have
FC 9.5
CC 0.25 again

Will do OCLT test this evening and early tomorrow.

My understanding of the drop tests is to count your drops until the last one results in no additional color change then subtract that last drop in your count. That is how I count.
Someone please feel free to chime in and correct me.
