Need help on blender fluid simulation >.<

Contests and Challenges

I made this new scene with fluid simulation in blender.

Somehow there's pretty obvious black border in the fluid near the ground.

First I thought it was because the number of light bounces isn't sufficient so I went to crank up transmission bounces(Using Glass shader for the fluid) to 1024, but still got those black borders...and then the water even starting stretching near the lower right place...

Could use some tips from great community >.<

    Could they be shadows? (I don't call myself an expert.) When I do a very quick fluid sim, the surface of the fluid doesn't exactly match the surface of the ground, and I get shadows around the edges. Also the edges get very thin.

    I tried to cut off shadows of my water and it just turned out to be not very realistic. And water somehow flickering a lot.
