I'm also going on vacation for 10 days. Bring your FC up to SLAM level right before you leave. That and the pucks in the floater should keep the pool in decent shape. If you have a friend or neighbor who can drop by to check skimmers and add a gallon or two of liquid chlorine it'd help. Also agree with Maddie that your CYA should be at 50 to provide more sun protection for the chlorine. Might be up there when you return!
