Thanks for the info. I figured dumping might be the easiest fix. Can you tell me if I can just continue with the BBB method once I refill? That's the three main things I need to maintain in addition to the recommended chlorine from Sam's club? Wasn't sure if that was mainly for the saltwater guys or for everyone. And wasn't sure if you could strictly stick with that or if you had to change the routine at some point? I am going to get the recommended test kit as well as the replacement filters. So glad you guys are willing to share your insight with folks like me. Thanks again.
