DSC-T1 with Marine Pack Questions

Hi,

I have a Sony DSC-T1 with Marinapack housing (MPK_THA) and the RED filter.

Next week i go on holiday and shoot my first underwaterphotos. Can someone tell me if i have to change something in my camera to shoot better photos.

for example: wihite balance, iso?

I saw that "splasch" shoot some nice photos with the same camera.
