The flow rate depends on what you are using it for. Most UV sterilizers come with a manual that should have a chart or something showing what flow rate to use for each kill type. Generally the lower the flow rate the higher the killing power.

I’ve been using UV lights for 5 years and am quite convinced they can improve water quality as well as water clarity…

I run mine at:

10 gph per 1W of UV…
1W of UV per 10 gal of tank volume…

This is to kill parasites as well as improve water clarity.

For aquarium use I feel if you are going to invest in a UV you might as well get the most out of it and therefore I suggest using the above rates…

For use on an outdoor pond to remove green water use the same suggested rates only change the 1W to ¼ W

It's also suggested to change out the bulb every year... I see nothing wrong with buying such a unit used, although I would replace the bulb...
