Howdy,
I am interested in constructing features such as rocky walls, caves, even simulations of tree roots including terraced structures in a freshwater tank. Kind of like making a 3-D backwall but with areas for plants, driftwood, etc. I've received mixed reports on the use of styrofoam and concrete (without lime). Even making a mound in the tank seems to be difficult, as the gravel or sand will, over time, slip downward.
Any help from wise folks?
Thanks,
Paul
