Refugium in Nano cube?

[doc308]

I have a nano 24 and have been reading about people setting up refugiums in the 2nd chamber of their nano cubes. I can easily remove the back wall black tape and set up lighting to accomodate all the chaeto it can hold. My main question is can the 2nd chamber hold enough chaeto to be effective?
Thanks!

It can hold a surprising amount, well worth the effort IMO.

Thank you so much!
I'm not sure how much to buy, but I'll fill a couple of fish baggies.
