I'm going to look at tanks this weekend and hopefully getting 3+ 55 Gallon tanks. I'm "not" going to try setting them all up at once. 
I want to start with a Fully Planted one. I love the look of these.
I'm starting to piece together what I need, since one way or another I'm getting a big tank this weekend (if not these I will go get that 80 from Petsmart I was looking at).
What I'm trying to figure out is should I go sand, natural gravel, colored gravel
? If gravel, what size, etc...
Thanks for any advice.
