This is my first year with a pool and first year with the TFPC method. I think I finished my SLAM successfully in early May- passed the three requirements, and everything still looks good. I add 1-2 quarts of bleach daily to maintain my FC level and <1 CC level. I continue to read about people who are currently SLAMming or completed but still have some issues, which got me thinking- what would be the first indication that the SLAM wasn't completed properly (assuming you incorrectly thought you passed the three SLAM requirements)? Would it be a high CC, adding too much bleach, an algae bloom, cloudy water, any of the above, or something else? This is more for my 'future reference' knowledge....
