Going on vacation first thing tomorrow morning and no one to help with pool, so using pucks while away. Will be gone for 10 days. Just opened a chlorine floater I ordered online only to find out that it is the wrong size -- it looks like it is made for the tiny 1" tablets. No pool stores near me are open right now! Now what? Can I put a couple pucks in a sock and hang in front of the return jet like I would for granular CYA?
