Welcome
Please follow the advice of the contributors here. I used BQ for years. My conversion is almost finished and my pool already looks better than it has for years. This method works! One pool store wanted to sell me $300 worth of chem. (special shock) for the procedure. So far, I've used less than $100 of bleach. Even buying the T100 test kit and contributing to this site, I'm getting off "cheap".
Good luck with your conversion!
