Figured while I sit here eating tacos I figured I'd share my project from last week. My wife and I moved into a new home about a year ago, and from day 1 I had my 40B setup and running. Thankfully there is a bathroom about 20 feet from this tank. So water changes haven't been much of a hassle....but...I wanted something easier. I found this little hole behind my aquarium that ran straight down into the basement and next to my water line. So I thought, "huh, why not run a water line to my tank!?" Well guess what...that's what I did!! I control the hot and cold water in the basement and put a little twisty knob thing next to the tank to open the pipes. Works like a charm!! For the life of me, I couldn't find any google results on people doing this, though I'm sure others have. Took a few hours but it's kinda nice having such easy access to water!! Anyone else do this?! BTW all that other pipe is my CO2 reactor and such.
