Little bug in sump id help

[Josh1980]

I found two of these little guys stuck to the glass of my sump. Not sure how well you will be able to see them from the pics. They are tine with long legs kind of remind me of a spider bed and kind of clear in color. Any ideas? And good or bad to have around?

Small Spaghetti worms perhaps.
