I'm at work so i don't have the time to answer as I want to. Your questions are good questions, not dumb ones, and I appologize for short changing you.

Search the forum for the new way to add CYA. It's hilarious and WILL work extremely well (yes, lady's hose).

Bleach means bleach. Liquid Chorine in a jug, but sold in your supermarket as bleach. Plain, generic, unscented laundry bleach. Ultra is OK. Plain / Regular is 5.25% chlorine, Ultra is 6% Chlorine. Pool store "Liquid Chlorine" is usually 6% in gallons jugs so it's EXACTLY the same as ultra bleach. Sometimes it's 10% or 12.5% which is, of course, twice as strong, but very unstable an breaks down rapidly if you don't use up.

Granules (powder) is either di-chlor powder or cal-hypo powder. Sometimes tri-chlor powder. These are types, not brands. Go to the top of the pool testing forum and the chlorine forum and read the stickied threads there--they may help.

Wish I had time for more....
