Brettski,
Thanks for the link. I do remember it, but enjoyed reading it again. I don't think I have a leak, but the water level is dropping, so I wanted to share with everyone and ask for opinions.
When the water level was lower, it didn't change at all, now it's slowly dropping, so something has changed. I think it's normal and not a problem right now, but I'm not very knowledgable on these things.
burgermeister and bobad,
Thanks.
Eddie
