6% Chlorine Bleach is $2.98 for 1.42 gallons.
Calcium Hpyochlorite 68% is $16.99 for 5lbs at local pool store.

My pool salt level right now is testing too high (3900+). Not a big deal at the moment since my salt cell is broken and it's supposed to rain for 3 straight days.

I need to take my pool to shock level, my CYA is 15ppm.

My pool is gunite and my hardness level is testing at 180ppm.

Should I go for the bleach or the Calcium Hypochlorite? And how much will I need to get it up to shock level? My chlorine level right now is less than 2ppm.

Thanks,
Darren
