Also, the potting mix decomposes over time, my mountainous aquascape is now pretty much flat, areas that used to have 6 inches of substrate are now just the top layer with the wood chips working their way to the surface every time the substrate gets disturbed by my trumpets.
In my 10 gallon tank I have this Potting mix and MTS and never have this problem. The wood chips stay below my sand cap which is about 1/2" deep.
Now on the sides you can see where the two layers have begun to mix together. The depth of the sand in front of the dirt isn't that deep though. Which probably explains the mixing together.
