I am planning to layout my planted tank soon. The aquascape that I am thinking has a slope on one side with HC planted, separate by something that resembles a "river" (amid a low tech one, thinking of just using a dif color substrate), then some mid/larger plants on the other side.
Question is, how do I best define a boundary such that the HC will not propagate to the river/the otherside? What's the best way?
