So I've made a decision:
I am going to make a complete rock tank, meaning not only will the back and partial back be rock, but also the floor. The idea is to make it look like the side of a real-life sized reef wall.
Thus far I am thinking the base unit (Rock Floor, if you will) will have a PVC skeleton with eggcrate. I will be using the PVC to be output pipes to blow out the floor, so detritus doesn't stay there. The outer edges of the floor wall will have rock lips (via extending eggcrate), hiding the actual bottom from viewers. The rock wall unit itself will not be flat but varied, just like a real rock wall shelf.
The rock floor will be split into two individual pieces, each with an output on the PVC structure. This makes the total rock structure four pieces, and considering how lite my rock is, works out perfect for both assembly and dis-assembly. The four individual pieces are small enough that I can fit them into totes (With corals still attached) should I need to move the tank. What's neat about this is that I never have to worry about getting the corals used to the lights just because the tank had to be torn down and set back up again. No accidental destruction or anything like that. The con to all of this is that if choose to have a new structure (Be it for one or more pieces of the structure), I'll have to destroy the piece (To remove the corals) and build a new one. This doesn't bother me too much as the goal is not to mess with the tank too much anyway.
I now have to buy some wood to make a model 40Br to cast in. I need to make sure everything fits and simply going by measurements ain't going to cut it. I now have purpose while waiting for my experiment rock to finish, hurrah! I will be going to Greenville tomorrow, which means I can pick up some eggcrate (There is none here in my city). I'll hopefully have the skeleton pieces of the bottom done tomorrow. I'm hoping to cast both pieces in rock on Sunday (Warmer temps).
