It does its job of keeping the drain clear, but it’s pealing and almost looks like the metals bubbling

The media could not be loaded. It's what I've been looking for for my roof drain..My only concern is, the water had to get deep enough to rise above the flat bottom edge to flow through the slats. This is about half an inch I'm guessing.But it will do its job well, and help prevent my drain from clogging.UPDATE: I cut notches along the bottom edge to prevent standing water. See image and video
