The tank does not have to be "filled" in order to get consistent, predictable results. Enough chemistry to cover the entire reel is sufficient. However, it is usually recommended that you put in as many reels as the tank will hold to keep a single reel from sliding from one end of the tank to the other. This isn't a problem with a one-reel tank but obviously would occur with a single reel in a two reel tank. On a related note, one thing I have found annoying about some plastic tank/reel setups is that a two-reel tank (for instance) will hold 17 or 18 ounces of chemistry. If you mix chemistry in small batches as I do this means that you can wind up with four or five ounces of developer left; not enough to develop a single roll. And since I prefer to mix a fresh batch of developer rather than combining batches, this small excess is discarded. I'm just anal enough so that this offends my sense of neatness and order :) >if I expect to process only one reel most of the time.
