I have never had a vortex tip over on me.  The newer ones come with a flat
bottom holder for the glass canister.  Yes, they run forever.  Karen, I do
not use the vortex for any plant tanks except when first setting them up to
cure that inital cloudyness.  I only use them for monthly servicing of
customers non-plant tanks.  Like you said, a plant tank will clear itself
within an hour.  I have found vortex filters to be quite easy to setup.
They are kind of a pain to move from tank to tank although, but at 400gph,
the time saved in clearing the tank more than makes up for the time it takes
to move it. I am of course assuming the tanks are separated by more than a
few feet.  It is very easy to simply shut the filter off for 30seconds while
you move it to the next adjacent tank.  If anyone has any questions or needs
some tips on priming, please email me.
