NO. I have a small tank that i develop two rolls of 35mm in and it dose not take all of the dev etc to process the rolls. I store them in 16.9 oz plastic water battles. and squeeze the bottle intel the liquid is all the way to the top and then tighten the cap. seems to work good so far and this is the second kit that i have used in this manner. the developer i put in a small brown plastic bottle. the first kit i taped the developer bottle with duck tape.
