Thanks Ben.

I did as you suggested and I do see an improvement in circulation. I had tried to adjust it before but the darn thing was on pretty tight, but I got a jar lid opener and think that it did the trick, but I'll monitor. I saw an adjustable eyeball (in a hayward vacuum video) that stuck out about an inch from the pool wall but it was hard to find on the internet and probably was going to be more than I would be willing to spend. I'm glad to have a simple solution.

Thanks again.
