I'm in the first week of a 2 week iron stain removal routine (26K vynil liner IG). Per Ben's recommendations, I've brought the FC and PH down, got the stain off the the liner (used Pool Stain Treat - Oxalic Acid) and am now slowly bringing the PH up. I've been keeping the FC low, at 0~1.5PPM with tri-chlor tabs in the skimmer (pump/filter running 24x7) and have been adding polyquat regularly. The liner is clean and pool never looked so good!
In another day or two my PH will be up high enough so I can move onto the 2nd phase and start increasing the FC. I'll take the tri-chlor out of the skimmer and start to add bleach/Cal-Hypo.
My question is... I can't seem to find Cal-Hypo pucks anywhere around me. I can find the granules though... If I want to raise the FC slowly... how and at what rate should I be adding the Cal-Hypo granules through the skimmer? What if I use bleach? How do I slowly add bleach?
Additionally, why is it that Cal-Hypo or bleach is recommended for this process? My CYA is low (~25). Can't I just use Tri-Chlor tabs in the skimmer? Thanks!
