Welcome to our forum.
Perhaps the most effective post that I have ever read was a few months ago. The poster said that new tub owners always tend to over chemical their tub, causing erly drains. .
I'm going to take credit for that one That's been my mantra the past year or so. I remember that being me when I started. What ever the case, glad we could help.
Not to argue, But I thought that was "Cha's Law" ?
