Is my return pump powerful enough?

I'm worried my pump isn't powerful enough...
I'm finally getting the last bits together for my tank, and I'm using 1inch PVC plumbing. My tank is 33gal, so can a Eheim Compact+ 2000 handle the flow rate? Or is it to weak?

Your turnover rate is about 165 gph. Your pump has a controllable flow rate (265 to 528 gph as per so it should be fine since there's always a head pressure which reduces the flow rate.

I just set up a 34g with 3/4 inch return and same pump. I turn the pump to the lowest setting and turn it down also with a ball valve about 25% to 50%
