Sight Tube Design Released For 2012

NEW for 2012, the official Sight Tube Design has been updated to what I think is a much sleeker and attractive design. The elbows have been made more compact and less obtrusive which means the viewing length has been increased!
This mod can now be added to the Stage 1, 2, and 3 sizes.
Currently this mod adds $5 to the Base Cost of the tanks.

Thanks for all your input leading to this NEW Feature !
