A loose tank can be unnerving it's happened to me a few times.
I know it sounds silly but when I first started I wasn't lacing it through the buckle corrrectly. I can still get it wrong by not tightening it correctly, and these days I grab the back pack try and work the bcd up and down on the cylinder to check that its nice and tight. Removing your equipment and putting it on again is a pool exercise thats part of our basic pool training.
