Radion xr15w pro - settings for filming

[BlueRay33]

So I'd like to film some video of my tank or take pictures. But I can't seem to set the right graph and always comes out too purple/blue. When I turn up the whites, the sand is washed out. Anyone have any recommended settings for filming under a single radion xr15w pro G3?

I use both my iPhone7 and my DSLR

the entire image is overexposed. you do have too much blue/purple in that pic though. the sensor isnt processing it.
