Hi Roger,
Well, it depends on your setup, but a venturi can create very fine mist which is not as noticeable as you may think.
It is thought that the mist is beneficial to plants especially when they are in direct contact with it.
I have seen better growth closer to where my outlets are.
You can throttle the flow and the pump will not burn out as long as it doesn't run dry. That is where planning for plumbing is helpful. A few extra valves and such and you can create a bypass where any flow/pressure NOT used by the components is directed back to the tank.
I use the 533 as mechanical only. I removed the charcoal bag provided and run it empty that way. You could add bio-balls or ceramic rings instead, as there is room enough.
The 546 I do not have, but am thinking of adding one. If I do, it would go AFTER the 533 mech filter, or PRIOR to the venturi, as the bio canister does not cause as much reduction in flow/pressure to the venturi. It is more high flow than the 533.
Hope this helps.
