I have often used the expression, "I know enough to be dangerous," but when it comes to pools, before I found this place I was completely ignorant and therefore safe as a kitten. Essentially that means I was willing to accept what I read here as expert advice and follow it. I should say, then, that my ignorance of pool care was a strength I brought with me. Not so for many first time posters I have read here; they ask for advice, then believing they know mostly what they need to know, immediately ignore that advice and are, therefore, dangerous. All this is a round about way of saying thank you to the members here who have taken the time to answer many people's questions and made this site such a wonderful resource for those of us new to pool care.
