Adrian, did you have your camera to auto white balance? Have you tried, in Lightroom or Photoshop, to adjust the blue curve towards the bottom? This should reduce the blue in your image. Note: this is only doable in Lightroom 5.x.
Took my grandson to the Vancouver Aquarium. Fabulous tank full of jelly fish. But all my shots turned out very blue. Not sure why - tried adjusting white balance buy had to go to extremes to get anything close to the white color they appeared to be. In the end resorted to LR's default b&w setting (I think) to get the whites. Bit of a mystery, that I will continue to investigate
