Help Strange dark surface reflection at low viewing angles

Take a look this this: https://imgur.com/a/w8gOxxP

As the camera moves further from the fluid and the viewing angles gets lower, the more this dark overlay appears in the liquid's surface. It looks like a reflection, but it's not. If you look closely you cant actually see that it is more like a portal that renders everything behind the bucket mesh that the fluid is inside of. The faucet looks like a reflection, but you can see that the button is missing and it's actually showing the part that is behind the bucket. I removed all reflection probes from the scene to see if that had something to do with it, but this dark blob still showed up. Whatever this is happens in screen space, the darkness disappears as you move the fluid to the edges of the camera's fov. I'm using the default fluid renderer with nothing changed other than surface downsampling seen in the pictures, but I also reverted that to see if it would make a difference.

Hi!

This is probably just refraction. Refraction works by reading a opaque texture of whatever is behind the fluid (so this happens in screen space), and perturbing the read location by the fluid normal. Does this happen if you set the renderer's refraction parameter to zero?
