Do your buoyancy check before you get back on the boat at the end of the dive as follows:
1. Have a near-empty (500lbs) tank. If you come up with too much air defer until the next time you surface.
2. Surface after your dive.
3. Make sure ALL your air is out of your BC.
4. You should be able to hang VERTICALLY JUST UNDER the surface (the top of your head should be just under the surface of the water)
5. While doing this test, CROSS YOUR LEGS, place your left hand on your BC inflator (but do not use it) and your right hand across your chest. This prevents you from unconsciously finning or using your arms.
Breathe lightly and normally.
If you sink, you're too heavy.
If you float, you're too light.
If you hover with the top of your head about 6"-1' under the surface, you're golden.
If all the air is out of your BC, you now have a baseline that works for that gear configuration - make adjustments accordingly.
I did this and immediately ended up with 15lbs as my "base" weighting, and haven't had to change it since...
Whatever you need to make this test work, you need.....
Note that your breathing can and does change buoyancy, which is why you need to be relaxed and breathing normally.
