Universal faucet mounted aquarium filler (and vacuum)

I have been shopping around on line for a faucet mount from the Python company for a few days and I haven't found anything that I trust to fit my weird sink connector. I need to do a major water change on my 55 gallon because I'm going to start using sand as a substrate and I screwed up and didn't wash it well enough before putting it into the tank. I decided to build this because apparently spiller pets in Tuscaloosa has closed forever and I'm tired of waiting for a solution to come my way. Also, I have a helpless god complex that only a 55-gallon aquarium full of loyal subjects can quell. Here's what  I came up with. This submission would also fit unfortunately well on ThereIFixedIt.

PROTIP: Make sure you have a water aerator on your sink. Half of the reason I went to home depot was because I broke ours off trying to get the threading when i was planning on buying a sink mount and  pissed off my girlfriend, causing her to look at me like this.

I've found that using the tube to fill your aquarium is a lot less obtrusive and stirs the sand far less than the 5-gallon-bucketeer method.

Step 1 Materials

First of all, I went to big box last week and got a 20-foot nylon hose to replace the ~3 foot one my siphon came with. I definitely recommend this convenience regardless of whether or not you follow through with the rest of this instructible, as siphoning aquarium water directly into the street is far easier than into a bucket and then outside. This will be the first material. All part numbers are from Home Depot. It also bears mentioning that I bought a 3/8" barb x 3/8" barb coupler to connect the two pieces of vinyl tubing I have. That was 2 dollars.

- 1x 1/2" outer x 3/8" inner x 20' nylon tube, part # 42143620 (~$5.00)
- 1x  3/8" x 1/2" nylon hose barb to mip elbow, part # A-296 (~$3.00)
-  2x  1" hose clamp (~$.50 each)
-  1x trash 700c bike tube (free at your local bike shop)
