I'm running 2 XP4s on my 125. I think the 120 is only a 4' tank, so there may be some difference there.
Additionally, I run the outputs of the XP4s through locline Y and out 2 outlets that are directional. I find there to be plenty of flow in the tank like this, and I can control where it goes in 4 different places.
120 gallon filter question
Thanks for the feedback. I am going to stick with the 2 XP3s and address the flow with power heads later if needed.
I like the idea of the under substrate jets. I can put the pipes in during setup and just cap the openings until I am ready to hook it up. I will have to look into this option a little more.
