The light emitted from a uv bulb is both uv and near uv, meaning it has a
bluish cast. You should be able to see it through the clear end caps. If
you cannot see any light, then the bulb is bad or the ballast is bad. If
this is a new unit, take it back.

I'll have to see if I can find the pump flow, maybe it is too fast.
The bulb is clean, I removed and checked it yesterday, there was no
build up.

One issue I found... I cannot see any UV light. At the inlet and outlet
I have a section of clear pipe I have used to connect the outlet/inlet
to my pump/pond hose (it was too big for a standard garden hose size
and B&Q didnt have any adapters - I had to cut up my snorkel to make
it). So its night now, and I can bend the clear pipe connector down a
bit to look right into the UV clarifier outlet while the water is
flowing. It is completely dark, no light at all.

Yesterday I took the bulb out to look and it doesnt look like its
blown.

So could the bulb be faulty? Should I see UV light? I am not looking
long as I know its harmful.

If you cant see the light the only thing I can think of is my flow is
too fast.

Or am I expecting too much in 1 week? Should I give it more time?

Thanks for your replies.
