Remra HOB skimmer and micro bubbles

Another option (for the even lazier) is get a piece of filter foam a little wider than the outflow lip. Cut a slit down the middle of the foam and slip it over the lip.

Presto! No more bubbles.

I use bulk black foam so it's less noticeable. I rotate 3 pieces every half week or so to prevent nitrate buildup.
