Harvey,
I have some information for the negative buoyancy tanks on Type IX and IX/40 boats. I hope this helps in some small way.

The negative buoyancy tanks are, under war time conditions, carried half full, are completely flooded to accelerate a dive, and are blown at a depth of 9 to 11 meters, which is qualified by depending upon sea conditions or danger of attack. They are not, however, to be used when going deep, because of the resulting falling rate, inability to compensate at great depths, need to use compressed air in quantity, and resulting pressure in the boat.
