I thought I'd post an update on my pool. I had decided about a month ago to add the borax. Followed the directions posted on the site and had no issues. I noticed the water is crystal clear with a capital "C" and the pH is stable as a rock. I have a water feature and have had issues with pH rise. It was so bad I'd use about a gallon of muriatic acid every 2 weeks. I think I have added a quart in the last month so I'm really happy about that. The water feels and looks great and I would do it again in a heartbeat.
