I got my cya down to 100, still pretty high, but manageable. I will do another drain right before closing so that cya is lower for next year. I started SLAMMing my pool yesterday with chlorine.
Here is what I have so far:
FC= 40 ppm (holding fairly steady, not dropping much) FAS-DPD kit
CC= 1.5 ppm
(Everything else is normal.)
It is Day 2 and I don't really notice any color change, still green. About how many days can it take for the algae to turn gray/white? Is there a forum that has other people's algae battles with before, during and after pics? I would love to look through that to know I am not alone in my fight.
