Maybe a little, but the soil doesn't make it above the sand... I'll post a pic of my 10G asian one day to show you.
Some people who use gravel and topsoil (without the potting soil) treat the topsoil like old-style flourite...
Mix some substrate with topsoil (about 30% topsoil to 70% gravel/sand) and put about 2-3 inches in the bottom, with an inch of plain sand/gravel on top...
I don't do it that way, since my method works for me and potting soil is cheaper than substrate.
