"rock" question...
Just wondering if I can use any rock for my discus tank or it needs to be some kind of special rock. I guess my question really is - are there rocks that might be poisonous in the tank and release toxic substance?

Most rocks will be fine as long as you can can the difference between the sandstones/limestones and such that will buffer your water and the other rocks which are fine. Although talking about rocks holding poisons someone I know just discovered something very interesting about the gravel they were using(it is widely believed this gravle was inert) he found it was slightly porous or whatever it's called and could hold substances inside itself like carbonated, irons and others

corrct me if i am wrong but i am sure you should use a sample piece of rock and some vinigar in a small bowl
if they have a slow fiss reaction it means the rock will harden your water and it a better idea to leave it out
can someone confirm this

Yes your right but I think when i tried that the vinegar was too weak of an acid but usually you can tell.

Remember that the Amazon is a river, so any rocks in there would be rounded and worn smooth.
Sharp rocks with rough edges are not good in a discus tank. It's too easy for them to sustain severe damage if they take a fright and decide to dash thru the tank.
I personally prefer a nice piece of driftwood.

I have 3 good pieces of driftwood (relatively large) already. I just wanna have some variety as my tank is bare bottomed. Any other suggestions that I can leave in my bare bottomed discus tank?

Decorative pots filled with gravel and a nice plant added look good in a bare tank, as do plants attached to the driftwood, like java moss, java fern and anubis. Just tie them on with some cotton or fishing line till they become established.
You can still have the planted look, even in a bare bottom tank. :P
