rock for nanos/picos

[FLricordia]

IMO the best rock for a nano would be the lightest with great porosity. I have seen very dense rock in some nanos and it wont hold as much bacteria, plus there is actually less water in the tank as the rock displaces more of it. Every drop counts in a nano, and so much more a pico.
I didn't see an information thread here for those starting their first nano/pico? Might be a good thing to have one and include info that is essential?

Phishybusiness.com carries a rock called Bali. It is VERY porous and has sweet sizes and shapes. I use it in all my tanks.

They are very helpful and will be able to pick out the rock to your needs.
