    Check the Best Guess Chlorine Chart in my signature below for the correlation between CYA and needed chlorine levels. In your pool, each gallon (4 quarts) of 6% bleach will add about 2.5ppm of chlorine. Use that as a reference to help you figure out doses of bleach.

    Got my Taylor kit: What to do now? Here are my readings:

    FC = 8.2 (I still haven't put any chlorine or anything in it for 8 days now and I took the tablets out last Sat.)
    CC = 0 (because it didn''t turn pink when I added the 5 drops of R0003 - it stayed clear!)
    pH = 7.4
    TA = 130
    CH = 280
    CYA = ~ 110-120 (I kept redoing it with what was left in my little squirt bottle to re-check and that's where it was when the black dot was completely gone)
    Sat Index = .1

    Ok.

    + CYA>100 => keep your chlorine at 7 ppm or above.

    + Do NOT add any alkalinity plus or calcium hardness increase type products.

    + Give us an inventory on what chemicals you have left. I assume you have, or will return the tabs. You can use the 4n1, but because of the alum you may want to add it via your skimmer. Just make 110% sure that there are NO tabs in the skimmer, a feeder or anywhere else where the shock can touch them. Just make sure your chlorine stays above 7 ppm.

    + Do you have access to pool store liquid chlorine (commercial bleach) or cal hypo in a 50 or 100lb container?

    By the way, having a CC reading of 0 is good! That is what you want!
