OASE Filtoclear 8000 Pond Pressure Filter with UV-C Clarifier (2nd Generation)

Can this be connected to 2" schedule 40 pvc, either glued slip connectors or to a threaded fitting? I want to avoid using flex pipe and pipe clamps.

is the uv rated to kill germ like ich and others or is it just a clairafier .

What’s the largest pump it can safely handle ?

So why call it an 8000 when it will only handle 4000gph pump so you can charge more ?
