So I added 260oz of 6% bleach to get it towards the high end of the best guess chart.
I'll check tomorrow to see how it holds. However with the trees over my pool I always have to fight the FC due to organic matter in the pool.
Quick sanity check though:
In the instructions under Daily testing step 2 it says to add R-0003 (DPD) to test for chlorine. My kit came with R-0600 OTO for this. I think this is a typo as adding only R-0003 to the chlorine vial did not do anything.
