Just wanted to say thanks to all the admins and users who helped with my recent problem. After finally taking the time to review all the sight, BTW, for those who haven' done that you will learn so much, I have solved my chemistry problem and the pool looks better than it has all season! I would like to know more about the borates and am sure if I would just read MORE I would find it. Again many thanks and I'll be a platinum TFT supporter shortly.
