How to simulate this effect

Hello,

I'm currently working on some product shots and I'm having a hard time to simulate this effect of water using Canon 600RT speedlights. I have 3 at my disposal (See attached graphic). 1 strip softbox, two snoots and a number of portable softboxes.

I've attached what I would think in principle would be the best lighting setup (very basic and crude.

I would of thought to shoot the glass tank sitting above a colored card to give the color of the water but what I'm really after is that heavy black contrast on top of the water when it is stirred.

I think the trick might be having a black surface somewhere - perhaps opposite the light source and then perhaps add the colour in post.

Photographing water is like photographing any other shiny/reflective surface... what you will see is more about what it reflects. Put your main light where you want to see highlights. Put black card/fabric (negative lighting) where you want to see the black shadows. And light the blue BG separately with some distance between it and the water tank; it will show through areas that are not reflecting the main light/negative light.

Edit, adding the color in post can also work.

There's no simple answer to this, it depends very largely on the qualities of the product, it's reflectivity, shape and exactly what you want to achieve.
I made a basic video about this, quite a few years ago now, the video quality back then wasn't great but I hope that the principles shown will help you.
