I've noticed that my compressed air reserves diminish after torpedo attacks. Is compressed air used to flood/empty the tubes as well?

In american fleet boats, (probably the same for U-boats), they would first flood the tubes, by opening them. When they shot the torpedo, to replace the displaced weight, they shut the tubes immediately, then filled the tubes with compressed air to outset the lost weight from firing the torpedoes. And torpedoes weighed ALOT.
