Skimmer Over Flow

[wingedfish]

I just spent a week drying an area rug do to a skimmer. My problem was lack of maintenance. Haven't pulled and cleaned the skimmer in months and the needle wheel was collecting snails. I guess some came loose.

You may never find what caused it. Skimmers are very unpredictable. This is the reason for my lack of maintenance, "if it ain't broke, don't fix it" it was working so well!
