Red Sea drain issues?

[ScubaSkeets]

Hi folks!
I finished setting up my Red Sea Reefer this weekend. The drain line into the sump is bubbling and foaming up like crazy. Is this normal? Any idea how to fix it? Thanks!

I can’t see the video, but did you first open your gate valve all the way, then set your pump speed and finally dial back the gate valve?

My return pump runs @45%, and I have the gate valve adjusted so that the water in the overflow is right at the edge/lip of the emergency overflow.

I figured it out. Thanks
