Aquafuge on a 20g nano?

Im thinking about adding an Aquafuge to my standard 20 gallon nano.

What size should i get?
Has anyone used or heard of these? How well do they perform.

I am currently running a 60 Berlin airlift skimmer and 2 hob filters (which has surprisingly working very well for 2-3 years) 1 biowheel, 1 aqueon. I also have caulerpa planted in the tank.

I'm thinking about keeping one of the hobs with the Aquafuge, would this be alright?

Should I keep running my current skimmer or use the one that comes with the Aquafuge?

Sorry for soo many questions, nervous about switching when everything is pretty well.

 

"if it aint broke, don't fix it"

 

haha, your right. Forgot about "if it works, dont fix it"

 

I've had mine for 3 mos already with aqua c remora skimmer uv sterilizer and ecosystem mud as the substrate for the fuge chaeto and rubble rocks nd chemipure elite bag so far so good great way to go natural IMO u could go with the small or medium depending on how ur nano is stocked

 

I would go with the largest you can fit.
