Green pool, advice from local pool store?

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

+ 6% bleach is about 0.5lb / gallon, so . . . . 2.98 / (1.42 x 0.5) or ~$4.20/lb Cl2 equivalent
+ 68% cal hypo => 16.99 / (0.68 * 5) or ~$4.99/lb Cl2 equivalent.

So, the bleach is a bit cheaper and it's definitely easier to dissolve in cold water. The only problem is bulk. Dosing with bleach, each gallon will add about 1.7 ppm of chlorine to YOUR pool. At CYA = ~15 ppm, 6 gallons of bleach should be a good dose.

By the way, Waterbear is correct: the K1005 is NOT a complete kit. You'd probably be better off to go ahead and get a complete K2006. But, use your OTO kit in the meantime -- you did get one, right?
