So the problem here is that I agreed to purchase your old reactor long before I ever saw anything you planned to do with the new one.
How am I supposed to want that old one now?!
Beautiful work as usual, Weatherson. And thank you also for the help with the reservoir that's already sitting above my tank. As for this new reactor, I'm impressed with how the fresh water feeds into the bottom, all the way out at the purge valve. That's one less hole in the top, and one seriously clean fabrication.
I have a clarification request. Is the bottom funnel piece inside of the tube, or is it sandwiched between two pieces of tube? If it's inside, how much trial/error/measure/remeasure did that take, and how did you get the acrylic glue in there?!
