Now that one hell of a nice table! You have got some very good ideas there, I'm going to have to barrow a few of them. Great idea on separate tank and gantry setup.
Your tank is huge, why so deep?
The additive that you added to the tank, was it in the form of an orange powder that turn it that color and what did it cost you? I think I know what it is and may have an alternative source.
Great job!
