These bottles were stored inside but were about two years old. I bought new reagents and got a FC 3 using the same water sample I got a no chlorine reading from with my old reagents so these reagents do go bad over time.
Yeah, I think that is part of my problem. I've got two Taylor kits that are from 2005. The FAS-DPD test is great. Thanks, all, for the suggestion!
