I just wanted to say a huge thank you to the TFP community for all of the help and support this blog and site has been. I am like many others who have been frustrated by the "Pool Store" and the constant needing of extra chemicals to add with very little if any results. I inherited the pool I have when I purchased the house a few years ago and I always dread opening up the pool as i was faced with "the green swamp" and had to spend days and hours trying to clear it up. After finding this site last summer I am excited to say that when i took the cover off this year i was pleasantly surprised (picture below) and had to give a shout out to TFP for all I have learned. I am actually looking forward to this summer and enjoying the pool instead of killing myself fighting it. Thanks again and I am telling all of my pool owner friends to ditch the pool store and join TFP!!
