First test of season...what to do?

[TfromNC]

My bleach calculator says my volume is at 9720 gallons. The pool is 12x24 rectange IG 3' to 6' depth. I already bought the CYA. I wanted to wait to get some feedback before I added it to the pool. I will get some bleach and baking soda to have it on hand.

In a pool this size, each quart of 6% bleach will raise your cl by about 1.5ppm.

Go ahead and add some cya to the skimmer. Add enough per label directions to get to a reading of 30. Then, don't retest for it, add more or backwash for a week to give it plenty of time to dissolve.
