I struggled with chlorine awhile when I first started. Back then, Charlie didn't really get into that detail and no web forums… I was fortunate the LHBS guy knew his stuff. I still remember tasting the results of my first carbon filtered homebrew vividly. Incidently, my beers didn’t not display the typical band aid/medicinal off flavor. It was kinda a faint smoky, stale type flavor and I think that made it harder to diagnose.
