Foaming sump filter sock

[Sunshine2036]

My filter sock or reef diaper, is constantly foaming over the top and spashing my refugium light. Is there something I can 3d print or purchase to reduce the amount of bubbles/ foaming thata happening?

Got a picture of the sock placement so we get a better idea of your set up?
