29 Gallon Filtration

I would say 4-5 times, and hour. With planted tanks and filters, it's not really about providing Bio filtration with the filter so that's shouldn't be an issue. Filters are used for flow and mechanical filtration.

We worry most about flow, since a heavily planted tank can reduce the circulation of water quite a bit. So it's always better to go above and beyond the 4 tank cycles per hour. The Eheim has flow toggles so you can reduce flow if it ends up being too much. The fluval does not, or at least the 04' series doesn't.
