Small Return Pump

[BfishLpond78]

Hello all,

Looking to get a small return pump for a 25 gallon cube, will have about 3.5 feet of head pressure. This will be for a 1st grade classroom tank but would like some recommendations for a pump to supply decent turnover.

Thanks in advance

Can we ask, what kind of gph is the overflow? We gotta match that.

Sorry I don't know the exact GPH of the overflow, its Marinelands 25 gallon cube Reef Ready, 18x18x16. I believe the overflow line is 3/4 inch.
