Ceramic coasters!  I just found these on Amazon what do you think? I only need six. But they have that cork backing can I just peel that off or does that matter?

I would assume the adhesive is an issue.

Apart from slate, there is this stuff called "coral frag disks" that is essentially the same thing but may potentially raise KH.  So if you have a tank that benefits from some KH, those might work well.
