Isn't there some type of gray scale that you can point your camera at to set a custom white balance? I need to use it for aquarium work which is sometimes under very blue light.

There are lots of devices.
Get an 18% gray card from your local camera shop. :)

For use in an aquarium you might want a WhiBal, which is a plastic grey card so should stand up to immersion better than most of the alternatives.
