I have a 16x32 vinyl above ground pool, we just converted it to a salt water pool. PH is 7.2 chlorine is at 1.0 salt test was at 3400 alkalinity at a 50 CYA was at a 55..

Pool water is green! I am not for sure where to start!

You can't slam at that level of CYA, you will not be successful.

Do a diluted test and report back...at 100, it could be much higher than that...here are instructions

Use CYA Mixing vial...
Add pool water to bottom of sticker/line
Add tap water to top of sticker/line.
Shake.
Pour out half so mixture is to bottom of sticker/line.
Add reagent to top of sticker.
Shake.
Use CYA dot vial and get a readding, outside with back to sun and tube at waist level.
Pour back and forth a few times to see if you get the same result.
Double the result to get your actual CYA

You will need to replace water to bring down your CYA...diluted test will tell us how much.

Its above 30 and still seeing the dot with the diluted water test
 
Something is not right...with one of the two tests.

If it was 100, it should be at least 50 on the diluted test.

Describe in your words what you did...for each CYA test...
 
filled the red capped cya bottle filled it to 75 with pool water then filled the rest with the reagent shook and waited 30sec shook again then used the cya view tube put the drops in until I couldn’t see the black dot

Nooooo! Don't add CYA. Liquid STABILIZER is CYA. We don't want that higher...

Click on Free Chorine on the overview page. There is a circle next to the word SLAM. click it. It will give you a target SLAM FC. Below that it will tell you how much liquid CHLORINE you want to add
 
Something is way off. Go back to the main page and click the settings gear in the upper right corner and make sure your gallons is right. *edit. I reverse engineered it. Your pool is 154,000 gallons in your settings.

Fix that, then click on the FC tab for the FC dose. Slam for 60 CYA is 24 FC. Enter your current FC, your target (24) and the type of bleach you're using.

And don't feel stupid about botching the test. You dodged a HUGE bullet there. I'd take the goof and a much easier slam, any day of the week.
