I suggest you stop dumping stuff into your pool. 26lbs of bicarb sounds sounds beyond the pale to me, but it does explain the TA of 320 - you'll have to fix that at some point. Floc is of limited usefulness and can readily make things worse.
I see you've purchased a TF-100 which indicates to me that you are also asking for advice on TFP. I don't read TFP nor do I know what's in the TF-100 but I do know that they generally follow the method of poolcare taught here. I also know that trying to following the advice given by different sources often yields poor results.
