Dave,

You are right; I'm getting ahead of myself.
Sorry about that.
I'm just REALLY dying to use my pool (my kids are driving me nuts, too!); it is already so hot here! I saw where parts of the country were getting snow yesterday...

Ok, ok; I will stick with 4 gallons of bleach, but how often should I add it?
I added 4 last night, 5 this morning, and everything is still zero.
What type of test kit are you using for FC and TC? Is it DPD (comparator cell with pink colors) or FAS-DPD (titration test)? The reason I ask is that DPD can bleach out with high chlorine levels. I don't think this is what is happening. I think you just have a big chlorine demand and the only thing that will take care of it is to satisfy your pool's "hunger" for chlorine right now but it is one possiblity that sprung to mind to explain your FC of 0.
I am currently using a TAYLOR "Complete (High)" DPD drops kit.


I guess I will just "keep on, keeping on."
I really want to order Ben's test kit, but it will definitely have to wait until next month's paycheck! <sigh>
