Andy- I'm glad to hear that I can run it with the bubble.
My pool is starting to get yucky.

We haven't done any plumbing..we bought the house just over a year ago.

My husband picked up an impeller today from the pool store...and guess what?
It's the wrong one.
If the new impeller doesn't change things I'll "watch and wait" because frankly, this is makin' me nuts.
