Hi all, did the Ascorbic Acid treatment last Thursday/Friday - I used 6 lbs since the stains were really really bad.
Since Saturday I've dumped 6 gallons of 10% bleach and can't keep the FC up. I did the overnight test last night it was 4.5 - 5 ppm, then this morning before sunrise it was down below 2. Put another 64 oz in and tonight after all day in the sun it was back to 0.
CYA level is between 30-40, Ph is 7.5.
Not freaking out yet, just was wondering if there is some calculation of how much bleach it takes to neutralize the added AA.
Thanks in advance for responses and thoughts.
