When I spoke to DSA they said the difference between the standard DSA and the Ocean View is: the trim and taping of the silicone seams. Neither one is that important to me. Material, design, actual silicone spacing, etc. = all the same (according to DSA)

I also just got a Marineland cube and love it but boy the quick flow drain assemble that came with it is SO loud. The little 60g cube is 3 times as loud as the big 215 Ocean View with the mega-flow overflow kits
