I have used bleach since I found this forum a few years ago and it works great! I just got a new liner, the old one was faded really bad. My family insists that it faded due to my using bleach. I always poured the bleach thru the skimmer. Am I safe in continuing to use the bleach and is pouring it thru the skimmer okay? should I dilute it first? I just don't want to ruin my new liner! please adise. Thanks!
