All I wanted was in my back yard in NH was a small pool for my kids to keep cool in. I bought a 15'x3' Intex easy set pool, filled it up and turned the water brown! Devastated, I turned to the internet for help. If I hadn't found this forum I don't know what I would have done!!! I found the best information and my pool is now completely clear! Thanks to everyone who shares their knowledge and stories. Without this site, I would have probably given up and emptied the pool. I am now confident that I can set up the pool each year and maintain it with ease and for much less money using the BBB method. Thanks again!!!
