Powerhead in fuge?

I had one of my LFS guys tell me that putting a small nano size powerhead in your fuge is a good idea, so I've have had a tiny one in there for a month or so now. Not sure on the GPH, but it barley makes a current. Today I had another LFS look at me like I was nuts, says he never head of that. I don't really keep anything other than sand/LR/Macro in my fuge, although I think I'm going to get a mantis for in there soon.

Anybody else have opinions on this?

 

i have one in my 20 gal fuge. i read that chaeto likes a little current.

 

I imagine it's a good idea to have one for tumbling types of algae, like Chaeto and Caulerpa.

 

I too have one in my fuge. Perhaps he thought you meant sump?

 

I have a Korilla 1 in there. My chaeto grows like mad.

 

I have a knano I run in mine
