Wisdom teeth - ick! You can blame anything and everything on that! I'm so sorry you have to endure that experience. Me - I have no excuse! Just a dim-lit dim-wit. At least all this pool stuff is making me feel that way!

Thank you for bearing with my ignorance. I really appreciate it. As you know, pool stores are a crap-shoot.

Think testing 3-4x a day is OK - should I test more on a sunny day (today is overcast)?

Thank you again for your help - it is very much appreciated!
