Pump little giant

[Johndean]

Hi thanks for stopping by I am currently setting up my old 150 reef tank and recently purchased a LITTEL GIANT PUMP 4-MDQ-SC the pump has 1/2 inch discharge and was wondering if any one has used one let say 9 ft of head might be 800 GPH on my 150 reef ? will this be sufficient ?
Or do I send it back for the bigger one next size up is 4-MDQX-SC 1 inch in and 1 inch out thank for any advisee in advance.

I had one on my 110, but only 4 ft of head.
They are powerhouses but energy hogs.
Unless the sump is in your basement, there are more efficient DC options.

Its on the low end of "ok" but the 1" version would be a better choice given those 2 choices..

I ran a LG model 4 for a while. You have to look at the flow curves. The 1" models will pump more in lw pressure applications, but lose output more quickly with pressure.
