Wow..thanks for all the input. I'm going to test everything out with the two blocks in series and then go from there. Waiting for a few last parts from the UPS man today and then I can get going. A few additional points and questions...
After reading through the very helpfull and thorough
H2O Technologies Explained in the articles section, I'm going to add an air trap made from a sealed electrical box. Regarding the air trap...should the water level be above the entrance (upper, highest point) barb or below it?
Thanks again for all your assistance...I'll keep everyone posted on the outcome...specs for the project:
