Yep, will definitely work. I just added a 1.5" sea-swirl to our 750 acrylic with 8" perimeter bracing and used the included mounting bracket.
The mounting bracket is "C"-shaped and will work for either perimeter bracing or tank wall mounting. The bracket has screw holes on 2 sides, so to switch between perimeter and wall mounting you just unscrew it from the base of the sea-swirl, rotate it 90 degrees and re-attach.
