Welcome to the forum

If you did not put any CYA in your pool, you don't have any. It's hard to interpret your post but you might be reading the test backwards. In a new fill CYA should be 0 and with the view tube full, looking down thru the top, you should still see the black dot.

Please read "The "ABC's of Pool Water Chemistry" up in Pool School. That is the basic starting point.

Next, you will need to begin the SLAM process. There is an article in Pool School and you must follow every step.

Ask lots of questions and we'll all help you get the pool crystal clear

did the cya test again and i get CYA of 100 I don't think i am reading it wrong

 

[duraleigh]

There is no CYA in fill water from your hose. Do you have any idea where it may have come from?

 

[Toebog]

no idea that's what i don't understand i drained the pool to get rid of it and all the pool store crud in my water now i don't know what else to do trying to keep the slam process going with CYA of 100 will be a task

 

[CarolineM]

With the test, if you fill the view tube to the top can you still see the dot? Or are you losing sight of the dot at the 100 fill line.

I find it hard to believe that with only 3” of the original pool water left that it had that much CYA still left in it when mixed with fresh water.

 

[Toebog]

losing the Dot at the 100 line

i also did a 50/50 diluted test and lost the Dot at 50 then multiplied by 2 and i get 100 (hope that makes sense)

poolmath said to add 3 gallons of 6% bleach to get FC to 11 did that,and 6lbs of borax mule team 20 did that here are new numbers after an hour have not started to Slam yet trying to make sure i am reading the CYA right and I am pretty sure I am ......Pool is green BTW

FC 12
CC .5
PH 7.8
TA 100
CH 160
CYA 100

Ok if you are going to slam with a CYA of 100 your FC level will be 39. You want to start by adding enough muriatic acid to lower your PH to 7.2. Let it mix in with pump running for 15 minutes then test again. Once at 7.2 add enough liquid Chlorine/bleach to get to 39 FC. Keep your filter running, brush the bottom and sides as much as possible. Test the FC only as often as you can, every hour if possible, keeping adding Chlorine/bleach to keep your FC at 39. Use a 10 ml water sample, 1 scoop of the powder and divide the number of drops by .5 to get your FC If you have a removable ladder pull it out and check everywhere on it for Algae, it hides well in ladders.

Brush walls often, run a leaf rake or blind vacuum over the bottom tot try and get anything there out. You can also use 5ml sample and multiply by 1 (drops = FC) if you are bumping it that high.

 

[Toebog]

as of 4:15pm will check again in couple of hours. The FC has not dropped at all sense adding bleach at 1:30 does that make sense

FC 42
CC 0

 

[mknauss]

No.
Can you post a picture of your pool?

 

[Toebog]

FC 32.5
CC .5

added the amount of bleach poolmath said to get it back to 39 will check again in the morning the CC test is tricky this time i saw just a hint of pink so i added one drop and it was gone

 

[Toebog]

this mornings readings added back in bleach. I can start to see bottom of pool going to brush walls and Floor today. So the FC is changing must have been a mis read on my part yesterday. here is the pic you wanted also

FC 30
CC .5

 

[Toebog]

this mornings readings brushed pool again this morning going to vacuum when i get home from work pool looking much much better this am added back in bleach as per poolmath

FC 34.5
CC .5

 

[Toebog]

so this mornings readings
FC 38.5
CC 0 to .5 had the slightest tint of pink

so my question is how long to slam pool this afternoon will be 3 days and the pool looks pretty clear this morning no visible alga anywhere. should i do an overnight test tonight or give the slam another day?

 

[duraleigh]

From the SLAM article in Pool School......
You are done when:

• CC is 0.5 or lower;
• overnight FC loss test shows a loss of 1.0 ppm or less);
• And the water is clear.
