use the little trick of adding some opacity to the specular material of the water, for a bonus, use a texture mix in the opacity with a noise generator and put something like 0,9 and 0,6 in the values, play with the scale of the noise and you'll get fake caustics on the go.... ;)

Also, your absorption is like 0.0001, which means that most of the light is absorbed after it has passed through 0.0001m of water, more accurately: 0.1mm of water, try increasing it ;)

you were using an HDRI to light the scene in the first one, on the second one you are using the sun.
The noise, use a turbulence node attach it to the first slot on a mix texture node, and play with the other 2 values till it looks correct.

well, doesn't matter if it's an HDRI or a white texture, same applies. The sun right now has a different aproach and as long as you don't do the opacity trick with it light won't go thru your objects.
