Hello all, I am a proud owner of a 27' round crystal clear trouble free pool thanks only to this site. I only wish I would have found this site prior to purchasing my pool from a store, live and learn. Thankfully I did join prior to the install, which was a nightmare, so I have not stepped back into the PS since. I purchased my TF-100 kit about a month before install and checked a hotels pool to get some practice in. The install was BS, the store used a sub contractor that took care of there customers first. After many angry calls I finally got the pool in and up. They wanted to send a crew over at 6:30pm, after a long day of installs, to finish mine. I would not allow it and told them that my village does not allow any construction after 7pm. I have not posted prior to today because I Have found all my questions answerd just by using the search here. So thank you very much .
