1/3 to 1/2, 1/2 being better is a decent flow for a tank turn over rate.
Run a Maxi jet 900-1200.
That's more than enough.
I have a Surge 6000, should push 600+GPH at 60w if you want.

It's a lot of pressure(4ft+) and a venturi line would be best(eg a Kent
venturi valve etc) plus you will lose even more flow rate teeing off the
return. Fine if you have extra flow etc.
Other wise a maxi jet+ 3x18 PVC etc with the output fed about 1/2" from the
return's suction side.

Did not make it over to get the plants driving past Miami, have too many
marine plants in tote.
Email me off list.
