Hello. Relatively new diver here who recently finished padi aow. I used most of my aow dives to improve my buoyancy skills and I have one question:
After establishing neutral buoyancy, your body still ascends or descends as you inhale or exhale. Maybe I inhaled too much or at the wrong moment, I started to ascend more than I would like and it became difficult to bring myself down again. This happened a few times during my dives and I had to pull the exhaust valve quickly to prevent myself from continuing to ascent.
Afterwards I asked my instructor that to avoid this problem, if it's better to remain slightly negative buoyant. With slightly negative buoyancy, you can be neutral when you inhale. When you exhale, you will descend but you can easily control it by kicking. And you don't need to worry about accidental ascending anymore. My instructor said it's ok.
I want to ask if this is a right approach to neutral buoyancy. If not, what's the problem here and what's the correct thing to do?
