Oooooohhhh gotcha. For the OTO, that's why the instructions say, look but don't write them down. I'm pretty sure that's what I was doing. Thanks!
I'm using the SimplePool app because I can select TFP parameters. It has TC and CC, but not FC.
I used to use the Pool Care app, and it has FC and CC. I can enter and set the TFP parameters - would that be better?
Thanks again for sitting through another newbie mistake.
