Is that a person in that tank? 

I discovered a couple of the surprisingly impressive things, Scott had quite the eye when it came to arranging the rock, and he picked up this aquatic foam, used for koi ponds, which allowed us to securely bond the rocks together. 

Note how the foam bulged up after drying. Once dried the foam was then picked out leaving a clean look yet enough still was left to secure the joints.

Another change that was made was to a 20,000K HQI Metal Halide lighting system. These lights really give the impression of being below the surface.

Now that the tank is cycled Scott is eager to begin adding livestock....
