I can't quite figure out the tubing thing: many sites recommend the
black spiral tubing, but in my mind, the ridges will inhibit water
flow compared to smooth tubing. I need 1.25" tubing. Is the
spiraling stuff really the best way to go? It seems expensive...

Thanks in advance.

The tubing use is clear polyehtylene, smooth tubing. You can buy it at any
hardware store.
