Noob to the forum. Looking for CYA advice

[PoolStored]

GOT IT! Based on test = OK. Slam target is 16.

Monday calculated and added 8lbs of dry acid to achieve a CYA of 30 in a 28k gallon pool.
Tuesday nights test resulted in 40 CYA in my now 22k gallon pool.

Did you add 8 pounds of dry acid or 8 pounds of stabilizer?
Two vastly different chemicals.

It is recommended NOT to use dry acid in a pool with a SWG.

Nice catch
Yes it was stablizer. Not sure why my thumbs typed dry acid...

8 pounds of stabilizer granules in 22,000 gallons will raise CYA by 44 and lower pH by abour 0.81
1gallon of liquid stabilizer (128 oz)will raise CYA by 17.

Exactly what product did you add?
How did you add it?

And if you are in the SLAM Process, why are you adjusting any levels except FC?

He is in SLAM process. He is not adjusting anything but FC. He had pool volume off, which we spent the last page sorting out. He did addition at start of slam with a larger pool volume, which meant he added 40ppm instead of 30. We are good...

Dry stabilizer in socks, go back a few pages and you can see his rig...

Ok, great!
So likely pool volume may be a bit over 22,000 gallons (8# = CYA 44), but still within the +/- 10 ppm of the CYA test.
