hey, i got the plenum and chetto in mine, i have a ~600gph pump on mine...the chetto isnt rolling, should it?
id say give it some time, my trates have been hovering ~20 since i moved from the 55->75, and the water's still looking good, except i cant get the skimmer to skim as much as i would like...i have a prizm pro deluxe on the top, and will have a berlin deluxe HO on the sump this weekend...i think things will work out for you.
