The VX2000 is capable of excellent results and the type of DV tape you use shouldn't matter as far as color or image quality since the video is stored digitally. However, you should stick with sony tapes in sony cameras because of materials compatibility and tape lubrication. That's another subject.
When you say you are using a blue water filter, is it the stock internal flip down filter that comes with the housing?
I would first try manually white balancing the camera at depth off a white reference with the filter in place. I have my fins painted white on top with white primer just for this purpose. I zoom in on a small area of white on my fin with incident light hitting it from a similar angle it will be hitting my subject and with lens to subject distance the same as well. Calibrate the white balance and then zoom out to wide and start shooting your subjects. Repeat if you change depth by 10 fsw up or down.
If the above works, then you're all set. If you still arent' satisfied try another filter. Amphibico has lots of other ones both internal and external. They are all pricey. I've used an external #35 blue water aqua color filter on the VH1000 housing and thought it was much much better than the internal flip down filter that came with that housing. I'm guessing the stock internal filter is a #20.
The filter number is the total number of feet of two sides of a triangle where the filter is designed to work 'best'. One side is the distance between the surface and the subject, the other is the distance between the camera and the subject. For example, if you're 33 feet deep and 2 feet from your subject horizontally, the total is 35. You'd ideally use a #35 filter. Or you could be 25 ft deep and 10 feet from your subject, still #35. It's not an exact requirement by any means. Just know that the higher the number, the more red the filter is putting back in.
Good luck,
Brian
