ATO Chamber or 'Fuge?

[SeaHorse_Fanatic]

I would also lean towards a fuge. I like my external ATO system (5 gallon salt bucket cause I know it won't dump a huge amount of fw into the system even if it malfunctions and easier to fill up). I have almost a third of my 90g wide sump set up as a fuge section, just before the return pump section so if I have any pods or live mysis there, they provide a free snack to my fish in the display once in a while, which I'm sure my fish love.
