Not really sure. Well, sorta...I just think that the Tunzes in my tank are too narrow of flow. They are amazing, don't get me wrong...esp with the controller. It's just that my tank is'nt really long enough to get the full effect of what these pumps can do. Which is why I may try modding the front housing to make the flow a little more broader. At any rate, the Vortechs aren't needed at all, just something to look into.
