Looking for video feedback

[Frank Jig]

Hello All,
I've been shooting several underwater videos and so far I'm OK with the results.
[video=youtube_share;u29m8KIJAVw]http://youtu.be/u29m8KIJAVw[/video]
I'm looking to improve the "true" colors. I've read about red or orange filters and have been debating about it. For example the wreck in that video is in about 160-170ft.
If I had a red/orange filter,
1) Would the color improve
2) Would I need additional lighting?
3) How "tough" is the backscatter glass? My GoPro really gets bounced around on the bottom...

If I did not use a filter, could the colors be "restored" with a pre/post production software?

Thanks

1 no, filters are good when there is still plenty of sunlight, just not red light. About the first 45 feet.

2 Yes, the more the better, and most lighting still only works when less than 4-5 feet from subject.

If you look at this video you can clearly see what lights can do. There are a few times where I turned them on and off so you can see the difference. You can also see some scenes where I had the lights pointed right or left with the whole scene viewable so you can see the difference. These are unprocessed clips straight from the camera. They are best if viewed with a HD monitor.

Big difference indeed!!!
I guess I'll try a lighting system first...
Thanks for your input!
