Nothing has changed in the last month (new skimmer was added). It was dead today

. The thing coming out the bigger of the 2 holes looked kind of like a tung (sp?) (I know they don't have such a thing

) Last night it was trying to snap shut but it couldn't... Not sure what happened... it was doing really well. I hope I didn't forget something or didn't do something I was supposed too!?
