Marie, here are my numbers as of this morning:

FC 12.5
CC0
PH 7.3 (down a bit from the rain yesterday, I assume)
Alk 90
CYA 35

So, I will just try going up to about 16, and maybe 17 max and cross my fingers I have no liner bleaching! Just plan on doing this through Monday, and reevaluate the mustard algae situation. It appears to be mostly gone at this point. Not sure if it is dead, alive or what, but the amt. is much less, and with running chlorine at 15 as often as I can for this last week, I would think it would be dead or nearly dead by now. I vacuumed this morning and will see what it looks like in the morning.

Thanks,
John
