Thanks Dave. Those who are pool savvy often forget that those of us who are newbies often do not know even the most basic of information. When we got our pool, they put it in and left. No one ever gave us ANY guidance on how to manage it. So when I found this site the other week, I found all the acronyms to be confusing and overwhelming if you don't know anything about the basics. That being said, I am now amazed at how quickly I learned (mostly with the help of Ben's test kit) and our conversion went beautifully, the water is unlike ever before! But it was kind of you to remember that there are some of us who need the basics spelled out to us first! Thank you again.
