Here's some more pictures of the tank.
A few of BB pics just for Bev
Right Side:

Notice the small pile of sand near the middle of the picture. That stuff is apparently a bit too heavy to get put up into the water column and down into my sump... there is no crude there, just sand.
Left Side:
I got pieces of rock and such covering most of the viewable part of the bottom of the tank on this side... but if you look from underneath the tank, its completely free of any kind of sand or crude.
Middle:

This is the only place where crude gathers in the main show tank, its easy to access, so I'm not complaining

Another shot of the right side of the tank.

Another shot of the left side of the tank.

Here's a shot of the entire setup I have for my tank... that spare tank on the side there is going to be my reservoir for top-offs while I'm on vacation... I figure 30 gallons worth of RO water should be more than enough for 3 weeks. Afterwards, I hope to turn that tank into some sort of fuge/frag combo tank. You can kind of see how cobbled up my setup really is... the only things I bought brand new were my lights, the mag950, the scwd, and the revolutions. Everything else was either given to me, or bought 2nd hand.

I found this bi-valve on one of the rocks I bought from Dez.
