Hi all. I assume this topic has been covered ad nauseam but I didn't find anything quickly. I'm getting a new 18"er. On the one it's replacing, I've kept the water pan filled with play sand. I love it because it acts as a heat sink but I still get a great bark. The only issue is that it weighs a ton and has, at times, slipped off the tabs, which is a mess. And the new pan is bigger I think. I thought I'd heard of people using clay flower pots or something as an alternative. Thoughts?
