Poll: What kind of substrate you guys using?

[ISFRAEL]

true! true! i buy something expensive for my aquarium at least once a week. BUT I NEVER REALLY NEED IT!

 

[Mantis the Menace]

I use about 2" of crushed coral in my tank.
My mantis has never tunneled so it hs never created a snow storm.

I use medium sized crushed coral. Its about 4-5 inches deep. My mantis dosent make snowstorms alot.
