Doesn't really matter if you are going to boil the water afterwards, that will sterilize it. If it is something you are adding to the fermenter after the boil, then yeah.
I used glass etching paste to permenantly mark my carboys every .5 gallons. This makes it easy to see, and it will not wash off with any cleaner or sanitizer.

That is a great idea. How exactly do you use glass etching paste?

you can get the etching paste at a craft or hobby store. then you just follow the directions. I jjust added 1/2 gallon at a time, let things stop sloshing, then carefully masked off a thin strip at the water level with 2 pieces of masking tape. You probally want to leave a thin strip of exposed glass about 1/8" wide x 2-3" long. Once you have all the levels you want etched masked off you clean the exposed area with rubbing alcohol. Once the area is clean and dry you carefully apply the etching cream. (be carefull not to get any cream on any areas you don't want etched). Avoid getting it on your skin, as it is a pretty powerfull acid. you let it sit for 5 min and then rinse with plenty of water. Once you remove the tape you will end up with frosted lines for each 1/2 gallon. If you want to go one step further, you can even get number stencils and mark each line.
Regarding the etching paste...a little goes a long way if you are just etching carboys. I have plenty left over if any of you local guys would like to borrow mine. I have stencils too. Just let me know.
