New to forum and pool maintenance. Stumbled across your site and have been reading for a week or so. My pool was a dark green mess. Quickly realized that I needed a test kit and ordered as I have always used pool store. Recent trips out of town led to my current mess ("knowledgeable" friend was supposedly caring for pool). Ordered my TF-100 and it arrived 2 days ago. Was "shocking" pool with liquid chlorine before test arrival. So....I'm trying to get my pond back to a pool. Eager to learn and become a happy pool owner!
