Help Simple and efficient way to make Obi Fluid rise/lower in a cylinder container

[zkkzkk32312]

hey,

yes I am using mesh colliders for the tank,
but its relatively low poly, only 150 verts and 98 tris.

so I tested it with Burst,
it starts with 20 fps but goes up to around 55 after a few seconds.
I shell keep tweaking the values on solver/blueprint.

do you have any suggestion on runtime particles adding/removing?
