Yes it will fit. Too much turbulance??
Well, I have 2 AC70's = 600gph as opposed to 500gph for the 110, on a 29, and I don't think it's too much at all.
But..............I tend to over filter.
I like the fact of having 2 smaller filters even though the GPH may be more, for redundacy issues. I even have a AC301 powerhead with quick filter in the tank as well.
