Here is a picture of the bag I bought:

On the back it says 100% sphagnum peat moss where it would list the ingredients.
This is what I saw when I opened it up:

The white dots are quite hard but crumbles like dust or fine sand when put under enough pressure. (They remind me of those silica crystals you get in bags with electronics)
Yes it's a little shaky image but it's harder to take pictures down a bag without blocking the light than you can imagine.
Finally got the tank inside, still waiting on my pump which was ordered on 9/22 from a guy on eBay, wouldn't recommend buying from maxpetsupply_com on eBay btw (no communication from him at all), but I already placed the waterfall in there and glued my air plants.

Starting to look quite nice now, can't wait to get the substrate done and look how the river and waterfall will look when running.
