Water flow for 36x24x18 65 gallon

Is 1000 gallon per hour from return pump enough? I also have a penguin 550 powerhead in the tank blowing sort of across the back wall.

 

[hnf2k]

yes.

That is plenty of flow for your 65g at 1000gph that gives you 15.3x turnover. Plus your punguin. Most people suggest a turnover rate between 10x - 20x
