Baquacil to Chlorine - something wrong

[SwiminNJ]

MJONES -

This restart is a non-chlorine shock. They had me add a total of about 30 bags (1 pound bags) over a 2 week period. My readings went from 90ppm to 40 ppm to 30ppm to 10ppm to 0 (not really 0, because the pool turned so green for 2 days after adding bleach, but test read 0).

I poured it directly into the skimmer. I then cleaned the sand filter, and backwashed. It then only took me 3 gallons of 12% bleach, and about 12 gallons of 6% bleach to finally have it crystal clear.

how did you clean your sand filter?

Once your conversion is complete, you're going to need to change your sand.
