Some questions...

How do you add Bleach? into the skimmer? the deep end of the pool?
Skimmer...pump running

How often? Duh... as often as the water requires. So I knew that.. But how often is that? With the tri-chlor tablets, I just dialed the chlorinator up/down depending on the test results. But since there isn't the continuous feeding that one gets with a chlorinator or a floatee, how often can one expect to have to add chlorine once the switch is made?
Short answer...almost daily depending on the test results

How much? Duh... as much as the water requires. So I knew that too... but here in upatate, NY (season is June through August with temps generally between high 60s to mid 80s during this perios), how much bleach can I expect to go through is a season?
How big is your pool? How many people swim? Does it get full sun? etc. etc.

It's generally been $4/day to run the pool around here ($2 to run the pump and $2 for the chemicals... mostly the tablets). Can I expect to save significant $$$ by switching to the 3 Bs?
No, not huge amounts but significant. You'll also head off a future problem if you've only used pucks to this point.
