Red Sea 525/625 G2 Return Pipe Size?

[Villious]

Can anyone tell me what the return pvc pipe size is on a Red Sea 525/625 G2? I've looked and looked, but can't find any data on it. That would be the Y pipe under the tank.
Thank you.

On my 750XXL v3 it's a 1.25" to 2x 3/4".

Looking at this picture, the return pipes look the same diameter from the pump connection to the bottom of the tank?

Yeah, that looks like 3/4" diameter. On mine both 3/4" return pipes extend down to just above the return pump chamber. So you have the option of running a pair of return pumps or both with the aforementioned 1.25">2x 3/4" Y-split.

Awesome. Thank you!

It's NOT 3/4. I cur my return pipe to plumb in a UV, and the red sea pipe is smaller than a 3/4 inch PVC. It will not fit 3/4 inch pvc fittings.

Did you ever figure out what diameter it is? I'd like to do modify mine also.

If its some crazy proprietary diameter, can we replace the entire assembly and screw in a new connector?
