I could not figure out how to post my own question so I am going to add it here.
I finally decided to change from Bacquacil to Chlorine. I started 9 days ago and the pool is failry clear but not quite there yet. My overnight FC is 0, TC is 4 and PH is 8. Yesterday we took the ladder out and cleaned it . I t had brownish slime. Is it time to change the filter? When do I know I am done and we can swim again?
This website has been a great help with the conversion.
