ATO Chamber or 'Fuge?

[ronau]

Hello,

I have an ~7 gallon chamber in my new sump that was meant for an ATO reservoir, I had it notched so it would overflow into the skimmer chamber. Now would you use it for an ATO reservoir or a 'fuge? I am leaning towards a 'fuge since it' would be easier to set up an external ATO reservoir than a 'fuge.

Thanks,

Ron
