Good to know, thanks for the heads up.

The pool guy came by today (normally comes on Wednesday or Friday...maybe he didn't come last week is all I can think of, I didn't get an answer out of him). Anyways, his English isn't the best, but he told me something is wrong with the filter itself today. He brought his own and him and his coworker were working more on the pool than usual, so that was good to see. He said that he'll have to come by next week because he thinks something is in the DE tank itself? I couldn't make out much of what he was saying, but he said that sand was coming out of the filter if that makes any sense? When I thought it was a sand filter, it made sense...but now that I know it's a DE filter, I'm at a loss. I'm thinking I'll keep him around a bit longer to get all this sorted out!
