Has anyone here know what this product is? Being a Noob, I used it last year, with a Nature 2, and it seemed to work fine. After further research, I have decided to do the BBB method. I am not sure what effect the Pool Genie chemical will have on the water as I raise the chlorine levels. I will also not buy anymore Nature 2 cartridges. It is time to used science when maintaining my pool instead of magic and money. Taylor 2006 test kit is on the way.
