DOesnt all glass own oceanic? so the tanks area really made by the same company?
I have oceanic, I know people who have gotten the new all glass with the mega flow and like but hate it, they say it is hard to clean but you get good flow..
I have also seen the price difference, and noticed oceanis have the mega flow also now, least from what I saw at my LFS
I also prefer oceanie because the brace in the middle is glass, on a all glass it is plastic, on bigger tanks I see the braces falling because of the top/light whatever weight.
I am getting a new tank and sticking with oceanic though, better quality with what was said above, thicker glass ect..
hope that helps some
