From what I understand you can use regular potting soil if it doesn't have added fertilizers. You'll also probably have to wait much longer before adding shrimp.

im using miracle grow organic potting mix in my tank right now
I can tell you that it has made the water yellow, there are lots of little floating particles, and the substrate seems mushy, not as solid as most other substrates
that being said, it works and looks normal
you HAVE to cap it with something, gravel, sand, something
if you dont you will wind up with all kinds or dirt and other floating particles in your water

You will want to wash is as much as possible and screen it for large wood and sticks and other fluff they have in there
having used this method its inexpensive and workable but I probably wont use it again

The organic miracle soil is the one to use.. I capped mine with pool filter sand and black blasting sand on top of that. I put my plants in right away before flooding.. It is a little messy to get it going but after a few months the tank is clear and the plants grown like crazy. I have shrimp and a few fish in it for over two years now with no problems.

I have Miracle grow organic in 3 tanks.. all capped with black sand blast sand.20/40 grit size . Plants grow great,, need at least 1 " of cap or it will leach. I found it best to screen out the big chunks so all you are using is the fines. Also wet it to the point of saturation before adding the cap, press down lightly to remove all air pockets.
It works just as well if you don't screen it, but it is messier when you pull a plant out,, lots of floaters and pieces all over the tank.. I often just cut the roots around the plant to reduce the mess..
Make sure you know the correct placement of your plants.. My first tank, almost 3 yrs ago is a jungle,, nothing is where it should be, and I would have to do a complete tear down to scape it correctly.. Plants grow great, fish love the arrangement, but it could look better...
