I went out with Dixie Divers on Sunday for what I had hoped would be some good visibility for photography. Instead viz. was pretty low and the water brown. Despite that I got some good results out of my GoPro cameras particularly using a snap on red filter. The shot above was taken in pretty poor light and visibility but still came out ok thanks to the Polar Pro filter I was using. I ran into a nice goliath grouper free diving through a culvert and got some good closeups on a green moray on the Marine as well.
Here is the video:

There are bunch of stills with comparison images with and without the filter along with some conclusions at:
