Adding to MGOPM

So this weekend I'm going to start another dirt tank. I'm using Miracle Grow Organic Potting Mix and I was wondering if I should add anything else to it. Should I add some iron chelate? Should I crush up a root tab or two and sprinkle it in the dirt?

I know MGOPM has nutrients in it but are there still beneficial things I can add to it? Thanks!

I was thinking the same thing for a future tank. Thinking about using some dolomite, red clay, and some potash like they use for mineralized topsoil setups.

I've tanked the bagged dirt mix a number of different ways.
Adding muriate of potash and clay to one flooded 3/16/2011 the results are good. That said,,, just the mix capped the same way flooded 4/29/2009 (still growing a nice crypt garden) resulted in the same good results.

If you have it or want to add it go for it but (imo) you will be hard pressed to prove it really makes a difference.
