Finally got the CYA under control.
Final numbers- CYA 55, FC 6, CC 0, PH 7.4, TA 60 Calcium 60. Water temp 60. Number look good but the CSI index seems high at -1.1. Do I need to raise my TA and CL before my final SLAM or can I leave for winter? Its a vinyl with a heater so not sure about the heater and the copper in it.
Next is a slam. I have not done one, so pool math says for my CYA use 24 for shock FC. Maintain until my OCLT drop is less than 1 PPM and CC is less than .5(mine is zero now). Pool is crystal clear no signs of any algae which I had 3 weeks ago(I kept chlorine around 30 2 weeks ago but CYA was very high maybe 180+ that seemed to get rid of it).
Thanks again to the forum I learned a lot since sept when I started BBB.
