Thanks for the comments
I was inspired by this cool uplifted granite that I walk by on my way to work. I know, it's NYC's Central Park and not Lake Tanganyika, but I really liked the way it looked.
I used extruded polystyrene insulation foam (the denser the better for carving), latex based Drylok and Quikrete cement coloring pigmentssashimimaster said:
Just use a lot of silicone and then squeeze and sort of rub the sheets together. Apply some weight while the silicone dries. The bigger the surface area the better. After I finished the carving I also pushed some bamboo skewers through the layers to sort of pin them together and provide some structural support. You can see some the bamboo skewers in this pic before I trimmed the ends off:
Go Heels. Though I actually left Chapel Hill a few months ago - thanks for the reminder to update my location.
did you mix the cement dye into the paint?
im from the uk and will be using g4 paint which is pretty much the same thing as drylock

After the drylock and tints dry do you have to cure it at all so nothing leaches into the tank water?
bummer you left Chapel Hill, but NYC is awesome as well.
@Birch999, I have tried and bought the green foam from michaels and dont waste your money. It is "open celled" and it extremely flaky. I tried painting a sample of it to see if it would change the outside of it and it did not. Also I think its overpriced. Specifically, i tested the stuff from the "floral arrangements" aisle. However, if you aren't able to get that insulated stuff thats denser, you can try polystyrene that doesn't have open cells like the stuff from a new tv box. I just put mine together and I'm using it as a false bottom rather than looks as the_deeb is doing, but all-in-all im pleased with how it behaves.
