Different Results With CYA Regent Refill?

Oh boy, so contacting TFT won't do any good then, huh?

It may. They should have an idea when your batch was bottled and who also got CYA reagents around that time. They are nice people who care about pools. Let's see what they do.
 
Just heard back from them. Rebecca is sending me another 8oz refill and including a batch number on the bottle.
How's that for customer service!

TFT are good people.
