Controlling Ascent Rate

[arcFlash]

I'm not sure we got a clear description of the issue. It sounds like you didn't dump air or you dumped everything and couldn't go up? Anyway, what you need is a dive buddy with 15 dive to show you what they 'just' figured out. Log some fun dives with them in the 0-30 foot range and just work it out together. Then both of you find others with 50 dives and learn something from them. 150, 500.... I know it's not a great answer but it's how it's done for most of us. This forum helps but most of us are too old to remember what it was like. Mine was 11 years ago and all I recall is crashing butt first into the muck in Square Lake and popping to the surface the next second. It was like I was a yo-yo. But I learned. 20 feet of water is a pretty safe place to work it out. Just keep your cool and think about why things are happening. Find the cause and the solution is usually obvious.
