I am located in Central Florida and new to TFP. Owned a house with a pool since 2008 and have been using the pool stores all the time. We have solar panels for the pool and my wife has decided that 92 was the right pool temperature. After recurring algae issues despite regular maintenance, I came to this site and purchased my professional kit, showing a CYA of 60. CYA is now under control and I look forward to maintaining my giant hot tub!
