Bidirectional tidal flow

[MitchM]

Hi Tony,
Thanks. Powerheads would be the easiest route, but at $800 per Vortech, of which I would need two (1" acrylic walls), I would rather try to incorporate it into either a closed loop setup or from the sump return.
If it was from the sump return I would need to either have the sump height at a level high enough to reduce drainback or have holes drilled in the supply tubes to prevent drainback to a lower level sump.
Right now I have my tank drilled for 4 1" seaswirls and I could eliminate 2 for this bidirectional flow idea.


sphelps,
I would prefer to keep the upper water layer moving with the seaswirls with less current at the mid and lowest level.

On Oceans Motions website they say they do some custom work, so I thought I would inquire.
