Would You Use These Tiles For Frags

[Sully32]

Would you use either of these tiles in place of frag plugs? I'm trying to have them sitting flat on a bare bottom. I have searched, and there are people using them and then others saying not to. It is only 30 gallons of water as opposed to people using them in much higher water volumes. I don't know if that will have any effect on the answer. I just figured if there is any toxicity to them then maybe the larger tanks are diluting it to negligible levels.

It may release certain minerals or what not. IMO not worth the risk. Just by the ceramic frag tiles.
