I was told on several occasions to slow down during dives.
I thought I was going slow enough, but my buddies didn't think so.
Thinking about it for a while I found that I was using finning as a crutch for my buoyancy control.
Working on buoyancy, and making sure after each kick I came to a complete stop while staying neutral, helped me to slow down.
I've also found that unless your in current you only need small ankle movements to move along a reef.
Now I don't get told to slow down....as much
Thanks for pointing out those options... I definitely stop every once in a while and try to "hover" just to work on my buoyancy but when I'm not doing that I definitely kick fully, though slowly. I'll try the smaller kicks and see if that helps.
