Flow through the fuge

[mr11]

Im setting up a new 65g tank with a Trigger Ruby 36 sump. I want to set up a refugium for the 1st time so now I'm trying to determine if I will have too much/too little flow with my current design. It's a 1" beananimal overflow system with 3/4" returns, pump is an eheim 1262. Without taking into account head pressure that will be about 11x my total water volume turnover. Does that sound adequate for what I'm trying to achieve? Am I missing anything?

I've read that chaetomorpha likes higher flow.
