     Yeah, I'm wondering if my gravel isn't deep enough.  I'm setting up a 
second 20 gallon tank for guppies, and I plan to have lots of plants in it 
and want to do it right from the start.  I'm wondering about different gravel 
or what I can put on the bottom.  I've heard that sand is alright to use.  I 
suppose sand wouldn't be good with an undergravel filter, but otherwise, is 
it recommended?
