Retest with a drops based kit and repost with current readings. I'm especially want to see the next alk reading. If your ph is 7.2, you need to watch it and not let it drop any further. If it were my pool, I'd probably add just a little Borax and bump the ph up to about 7.4. Also, if your cya really is 80, you'll need to run higher than normal chlorine levels or you'll risk another algae bloom. See the chart at the following link.
