One way I found that works quite well is inserting pieces of roofing slate 
into the substrate. I level about 2 inches of substrate and cut pieces of 
roofing slate in strips of 2 1/2", 3", and 3 1/2" wide. Cut enough pieces to 
each width so they will fit across the length of your aquarium.

Insert the pieces vertically into the substrate in ascending order from front 
to back. Fill the aquarium with the necessary substrate to achieve a slope 
from 3 1/2" in the back to 2" in the front. The slate will act as a barrier 
to prevent the substrate from leveling out. They will also act as stop to 
prevent plant runners (under the substrate) from spreading forward or
