If you begin using the trichlor pucks, I suggest calculation how many it would take to raise the CYA to the level you want, then retest CYA at that point. It may not have gotten that high, since there is some loss of CYA over time, but you do want to be on top of that. And you will keep up on daily or every other day tests of FC since depending on how it is added, you may need a small chlorine boost via bleach or something to keep the levels up. I do notice that TA is high, and MA could lower that which would also help keep pH from rising so fast.
