Diving Silfra - Which Colour Filter?

[NightFox]

Hi,

I'm hoping to have the chance to dive Silfra (Iceland) this summer, and want to use my GoPro to capture my dives. I'm not sure which colour filter I'd be best using though - red or magenta? I know red's normally best for blue water (tropical) and magenta for green (cold), but due to the purity of the water in Silfra I'm not sure what I should expect in terms of water colour and therefore which colour filter's going to be my best bet. Any advice?

Thanks,

Neil

Hi Neil,
I'll be diving in Silfra this summer, what filter did you end up using? How was the footage?
Thanks,
Tommy
