I built my salt water pool 8 years ago. I received limited instruction on pool maintenance from the builder. I have limped along for all this time listening to conflicting advice from the pool stores, until I had major issues with my suction side cleaner and a SWG failure. The result was a very green pool. I found TFP, installed the pool math app, bought a Taylor K2006, lots of liquid chlorine and my pool is back to being clear. I am still in process and will be replacing the SWG in the next few days but for the first time I have better knowledge on my pool chemistry and how to keep it balanced. I am very glad I found TFP and I appreciate all of the help
