Joined TFP a couple of weeks ago and have already learned LOADS! Since moving to a house with a green, cloudy pool 4 years ago and bringing it back to a clear, swimmable state I was proudly thinking that I had become a bit of an 'expert' in pool maintenance. I'm a bit more humble now
TFP has already taught me that I have been making many subtle mistakes (and some not-so-subtle ones!), and has shed light on some persistent problems that I wasn't previously able to understand nor correct.
Big thanks and respect to all expert and experienced contributors
