running Vortex filter all the time? What about this version?

[JackBlasto]

So I've read that Vortex filters can run all the time BUT that it creates such a strain on the fish because of the current that it's not realistic to do. OK, that makes sense BUT here's my thought. What about running it IN the sump, THUS it creates no current where the actual fish are, but is running all the time? Happy to hear anyones thoughts on this. Thanks
