Just an update for anyone who may have been following. After testing & shocking throughout the day yesterday (i think it was 5 or 6 times)- i am hopeful that the situation has been resolved. Tested this morning and FC was 6, CC was barley pink, probably .2- So hopefully i am good, i will retest again at the end of the day today to confirm again.
Two points i would like to share. 1. The last two or three shock treatments done i followed advice given and hit it HARD, more than the shock levels prescribed on the chart/pool calculator- i think that helped and was necessary in order to get the situation under control. 2. I ran out of bleach and used 73% Cal-Hypo for the last treatments. Now it could be that the problem would have been solved the same way with bleach or maybe the Cal-hypo helped out a bit since it also adds some CYA (i think).
just sharing my experience. thanks all for your help and advice!
