JasonLion said:Yes, for dichlor every 1 ppm of chlorine you add also adds 0.9 ppm of CYA.
After struggling with off-the-charts cya levels and 2 drain and fills I got my cya down to 50 but after a month or so of just bleach for chlorine, my cya level has dropped to 30-35. Would it be wise just to switch back to trichlor and dichlor that I have still to raise the cya back a bit or is that too long a process?
