ET1 said:What a great idea! I'd like to try that for my cory's. Is there a special kind of sand for this purpose?
I used an old bag of quickcrete playsand that I had gotten from home depot. The only down side was I had to wash, wash, disinfect (bec it was sitting around), wash wash wash. But luckily it was such a small amout it was easy to do. I never had any dust particles floating in my tank.
Good luck!
