Sizing new pump

[ChrisQ0904]

Random question, I'm setting up a new tank (deep blue 80g), and am trying to use what I already have. Would a fluval sp2 be strong enough as a return pump with about 3.5 ft head pressure?

Per the flow chart for that pump looking at around 490-500 gph , that would be fine

How much flow do you want.? The specs look like you will get 275 gph at 4.5 ft so you would get more than that with the 3.5 ft you stated.
