Beach tank fluid falls through ground and boundary?

Hello. Sorry if this is a nooby question, I've seen a lot of posts from this website and they've answered a lot of my questions. But this issue I can't seem to find an answer to. 

I have a default beach tank set up on a grid that is rotated. Barely anything is changed, except for the particle separation and particle radius scale. When I play the simulation, the water goes straight down through the static grid and disappears. There doesn't seem to be any wind affecting it to create waves, and no collisions. I'm not sure what I did wrong here? If anyone can help it will be greatly appreciated. 

The simulation works fine with higher particle separation, but as soon as I bring that down this happens.

Attached is a flipbook of the fluid simulation.

Thanks in advance.

Edit: I've extruded my terrain geometry and in the static object I've increased the uniform divisions. The geometry representation is set to Convex Hull. Still have the same result.
