Questions about flow

[kwirky]

I agree with you: normal powerheads take up a lot of tank realestate. But I like my new vortech. I wanted a clean look in my tiny 45g tank and a single vortech did the job. If you ran one on each side it would look cleaner than the pipes sticking out from a closed loop and then you could have wavy looking action that'll make the polyps of your LPS and softies look cool.

It's hard to directly flow from a closed loop unless you start using locline and then you're starting to get clutter in the tank again. Vortechs pretty much don't need to be pointed.
