    Ben:

    Very willing to learn based on updated info!!!

    1/ "Wojitowisc' journal article in the JPSI" seems to be what I found at jspsi.poolhelp.com/ARTICLES/JSPSI_V5N1_pp20-38.pdf and the table on chlorine is indeed informative though not very legible. Your best guess chart reads much easier ;-) Any pointer to "Obrien (1972, I think) and Wojitowisc (circa 2000) and his own extensive analysis published here" (I could not find this)?

    2/ Do you or Chem_Geek have a page summarizing updated recommendations kind of like what is on that page 44 of the Taylor guide but updated?

    Thank you!

    Simpler:

    When everything is fine, no algae is present, and the bather load is light, FC = 5% of CYA (0.05 x CYA ppm = FC ppm target).

    Under heavier load, 10%

    With green algae, 15% - 20% or -- long term -- to remove black algae.

    Mustard algae, 25% - 50%

    With borates > 60 ppm, and especially, with phosphates < 125 ppb (0.125 ppm), the algae treatment levels can be lowered.
