If you put a sponge below the rim of the OF you won't be disrupting the flow into it. That should keep anemones out and allow surface film to go in.
People tend to pick at minor details - I'm not referring to you or anyone else here - so I tend to add all the "exceptions" to my posts to avoid people dwelling on them. See? I just did it again and didn't realise it. I was just imagining someone reading that original post and writing, "The OF has intakes as well, you know." I wanted to avoid that.

Also, I didn't have sponge or floss on the egg crate when the anemone went over.
