Q: Pump for eheim UV reeflex 350?

[Simon_K]

Hello,
I've recently changed tanks (downsized to aqua nano 40, 55L volume), and in the process changed from a broken external filter (RIP) to the integrated back filter.

I'm now wondering how to set up my EHEIM UV Reeflex 350. Should I get an external pump? What flow rate should i be looking at?

I couldn't find any guidance in the documentation.

Been doing a bit more research, would this suit my needs?
