All great ideas! The primary reason I started this short thread is I need something to fill the tank. I hate holding my tank siphon backwards for a good 20 mins to fill my 48 gallon tank. A shower attached filler would be much more useful.
I will check Petsmart for the assembly parts. My shower is just a shower, no bathtub faucet. I pretty much need something to hook up to the shower, a section of tubing, and a cutoff valve. I'll see what I can find locally and post back with what I got working.
Thanks for everyone's input!
