SeR, I posted on your thread pictures of my 65. If you have the reef ready pre-drilled standard 65, it has an overflow of 600 gph. With that overflow, you cant have a pump that pumps at a higher rate than that.
Therefore, you can have a pump up to around 700 gph, because with head loss you will be less than the overflow. I had a Rio 1700+ and upgraded to a Mag7. I definitely recommend the Mag7.
