I literally just finished my SLAM this morning, and we are leaving town for a few days this evening. My CYA is currently at 30. I'm wondering if it would be a good idea to throw a puck of dichlor in my skimmer to keep the FC up and also increase my CYA a bit, since I planned on doing that anyway after the SLAM. We are returning Wednesday evening. If not dichlor, what other suggestions do you have for keeping my FC up in target range while we are gone?
