Well its pretty simple, I obtained some landscaping paving stones and some lace rock to hold it up and look cave-ish on the inside.
Basically its a large flat piece of sandstone that sits on top of the lace rock which holds back the soil behind it and beside it. It is like a table. I had to take the big rock to school and use a diamond rock saw to cut a piece of it off so that it would fit, but other than that you could make it yourself.
Build the rock table first, then add soil, then fill with water. It's pretty simple.
Things I learned were:
silicone it all together as a single piece, as mine lets soil in.
BN's and plecos like rear exits, so give them one before they dig up your plants and soil
if permanent, silicone it into your tank too... you want to create a soil dam all the way around either way. any holes you have will allow soil to come in and soil will come in under the thing also.
have a way to dig it out as dirt and dead snails, etc will get in there eventually, I usually siphon everything out into a bucket and check for living organisms.
be able to reach your hand in there comfortably without disturbing things
FYI, to cut rocks linearly with a chisel:
In lieu of a rock saw, what you can do is softly score a line all the way around the rock where you want it broken, doesn't matter what type of rock it is. Use a chisel and either scrape or lightly tap it all the way around. It needs about a 1/8" depth to the line. Secure and weigh down the rock on the side you do not want broken off. You want it so that all your force goes into the crack you are creating and hammer both the top and bottom of the rock with a chisel in the scored line you drew. This will create a fracture in the rock until it breaks in the way you want it. You want to be sure the main part of the rock can't move or you will probably bust the whole thing apart with a few strikes. Even doing this you can still screw up, so have a few backup rocks or rent a rock saw.
