Watermom,

Granules:
..calcium hypochlorite 47.6%
..other. 52.4
-------------------------------
Min avail chlorine. 45%

Shock:
Calcium hypochlorite. 52%
Other. 48%
-------------------------------

Tabs do not contain copper.

Yes, its a newly filled pool.

Started in April, all was good until May when I started keeping track of measurements.. prior to then I used the algaecide 1 time at start up, then shocked & stabilizer tab weekly. Granules as needed during the week. No clarifier.
Then the pool started to get cloudy late April as alkalinity & ph rose.

Hope this helps and I hope the potential culprit isn't hidden in those 'other' ingredients..

Thanks
Sam
