Two and a half gallon fuge

I'm working on setting up a 2.5g standalone fuge to grow Copepods, macro algae and the like. I have a very nice light picked out but I had a few questions. My tank does not allow for an overflow so this fuge has to be standalone. What kind of flow do I need? How long should the light be on? And how do I get the Copepods from the fuge to my main system?

Any help will be appreciated!

 

You could go with something like this. It just hangs on the tank and uses pumps to move water from tank to the fuge. I think it overflows back into the tank, this would allow copepods to move from the fuge to the tank

My tank does not allow for anything to hang on it. It's the biocube 29 HQI. I also cannot turn the back into a fuge thanks to the HQI light taking up all the space.
