Suggestion on editing photos in Photoshop(Elements)

[pm3009]

Hi

I installed Adobe's "Underwater" Action into Photoshop Elements 2, and it does a GREAT job on most of the photos (like the attached fish photos - I'm very happy with how they turned out)...but on some, like the attached shark photos, it looks like it adds too much red, causing the water to look purple-ish. I think the photo of the shark that is edited with the underwater action is far better than the original....but what is the easiest way to make the water look more blue than purple, and still keeping the shark the way it came out after the edit with the underwater action?

Thanks for any tips you can give me!!
Pam

Use curves if you have it.

You can also tweak in selective colours if you have that.

Not an elements user so not quite sure what is on the list.
