We are new owners of a 25k gallon in ground pool in New Jersey. The pool was just "opened" last week and there is dirt at the bottom of the pool. It collects all in one area- the deepest section of the pool that is only 5ft to 10ft across. There is not much debris falling from overhead trees because none are that close. Should we get a manual of automatic ("suction side" I think it's called) cleaner? We don't mind doing the cleaning manually occasionally, but realistically I don't think we're motivated to do it every week. We just converted to a salt generator (I'm not sure if this makes a difference). We're having our pool service guys (the same who installed the salt generator) come every other week all summer long. I'll apprecaite advice on this
