Looking good! I used to keep in my back pocket how much CYA was in a puck, but I forget off hand. Your alk looks fine, so you don't have to mess with that. Dave is right about the low pH of the pucks, so if you are running the feeder pretty hard, keep an eye on your pH. If it starts heading for 7.2, you'll want to add some borax to bring the pH back up.
