the trichlor won't hurt right now, but it adds CYA- you probably don't want to be over 40-50 ppm there, so quit using the pucks when the CYA gets there... it will also help reduce the pH, as you are on the high side right now!
I would add 1 jug of bleach, to get your FC above 3, and use the pucks to help hold it up until your CYA gets to 50, then use just bleach.
Keep an eye on the pH- add muriatic acid to lower it if it goes any higher, or add borax to raise it if it drops below 7.2 or 7.3...
