I came to this site in 2010 when my agp was installed. I started with pucks and finished that first season as a reader but not yet a believer. When we opened in spring 2011 I finally got the test kit and started using BBB since my cya was already at around 80 with less than a full season of pucks/shocking per the pool store. Since going with BBB last spring, I've never had to shock, my pool sparkles always and test numbers are right where they should be. Through water replacement slowly over this year and last year my cya is now at 50. This year we opened blue and pretty clear. I added some bleach and within a day we were crystal clear. I spend less than 5 min a day maintaining the pool.
I went into the pool store two weeks ago to buy a themometer ($6 the only money I spent at the pool store this year.) I could not believe the horrible advice they were giving. There were several people in line infront of me talking about how they are there every single day to have their water tested and have no idea what they were testing for or what the numbers meant. People were buying shock bags by the case. I just felt grateful for this site for giving me the information I needed to maintain the pool myself. We aren't huge DIY people but since we found TFP we are when it comes to the pool, I know we have saved a ton of money and headaches so THANK YOU!!!
