Color Curves is probably one of the best options. You can select each of the red/green/blue channels individualy. In the blue channel click somewhere near the middle of the diagonal line and drag down slightly. In the red channel raise the line slightly. Experiment ... a lot.

You can add more dots to the line to change different areas of the brightness range by different amounts. Each dot, including the lower left and upper right, have control lines that you can grab on to and use to bend the curve.

I spent a lot of time correcting underwater stills, and the best thing I can say is be very conservative. A little correction to clean up near-whites and bright closeups (if you were using lights or near the surface), and leave the rest deep blue/cyan, because that's how it was.

Underwater subjects at any distance from the camera or depth, esp. in lower or natural lighting, are impossible to correct because it is what photographers call a 'monochrome wash', and applying reds and yellows will muddy the whole scene. This is a situation where adjusting curves in post is almost completely ineffective because they are relatively flat and lacking in tonal range to begin with.

If you want to know how they do it on 'Nature' or 'Discovery', it is that they have very bright, very expensive, chromatic-tuned lighting. Hardly something any of us could afford.

If you want to post a 30 sec. clip of your raw video somewhere, a few of us may want to try our hand at correcting it.

To summarize: Correct a little for near-whites and brights, and leave the rest as it is.
