Hello,
Thought I'd give back to the community a bit since I've used this forum so much for research in my build.

Tank right out of the box. Exo-terra 18x18x24

Background "organic-ized" with black silicone\eco earth and false bottom/stream mocked up

Stream covered in great stuff foam with tubing installed, the start of the carving

Rocks glued into stream bed

Eco earth glued onto outside of stream

Underside of false bottom showing tubing zap strapped into place, connections and the flow control valve

False bottom in place with pvc spacers, tubing connected to pump via a quick release fitting

Top view of false bottom back in place

Retaining wall siliconed together, wet eco earth placed in and a plant thrown in for good measure

Finally finished - front view doors closed

Finally finished - side view

Finally finished - front view doors open
I have a foam filter over the intake of the pump, and I had to drill three relief holes by the output of the pump for two reasons, #1 to allow a "blow off" for the water to go when I restrict the pump with the valve (in retrospect I should have gone with a variable speed pump) and #2 to circulate the water near the rear of the tank.
The pump is easily accesable\servicable (thank goodness) by removing about 12 fairly large rocks on the left\front side of the tank. The right side rocks of the tank where the water flows into all stays stationary but the left half of the tank has a removable eggcrate section that allows me to pull out the pump completely if needed, change the filter material, adjust the flow or deal with any of the (MANY) problems that you're bound to encounter when dealing with a pump setup like this.
I read in a thread on this site before I started this build, "Take the amount of time you plan to spend on the build, times it by 2, take the amount of money you plan to spend on the build, times that by 4 and you'll be done your build". What a learning experience!! Thanks to every1 for already asking the questions that were going through my head.

Jake says thanks!
