After about a year of having it pump water to my display from my refugium, I finally decided to get off my lazy behind and clean my SEIO. And OMG! You would not believe the stuff in there! I swear there were at least 2 different species of vermetid snails, 3 to 4 different colors/species of sponges, a few feather dusters, and a LOT of just sludge. I don't know what makes the inside of a SEIO such a happy place for these things, but there were more in there than there were on any other 4 square inches of my refugium. And well, after cleaning it, it runs back and nearly full force (which had decreased to <50% force).
Anyway, I just thought I'd share this as a reminder to be sure to clean your pumps... stuff does grow and live in there!
