This is the first question the search bar has failed me on, so here it goes:
If my CYA is low, and I am using Trichlor to raise both FC and CYA, does the CYA reading happen quickly, or is it the same week long wait as if I had hung the stabilizer in the return with the sock method?
FC 1 (oops) CC .5
Added 14oz of Trichlor after this reading. Pool math says that should raise the CYA by 3.1
So I am guessing by adding another 28oz of Tricolor, as the FC needs to be raised, I will then be at a CYA of 30.
I ask, because I have added Tricolor a couple of times, and I don't see the CYA increase PoolMath says I should see. My notes say I added 40oz of Tricolor on 4/18 when I had a cya of 25.
