i still need to do a calcium test to see where im at with that but this sock it stuff doesnt have any cya so i dont have to worry about that.

im just wondering how they match up price wise.

i was just crunching some numbers and i see that 182 oz of bleach at 6% would equate to 10.92 oz of chlorine per bottle. Multiply that by 3 and I get about 32.76 oz of chlorine for each 7 bucks i spend.

compare that to 5 lbs (80oz) of sock it at 45% chlorine and i get 36 oz of chlorine.

so essentially it is 36oz of chlorine at 12 bucks vs. 33 oz of chlorine at 7 bucks.

I think i'll use the two 5 lb boxes of sock it initially and go to bleach because it will save me 5 bucks (and not add any more calcium)

Thanks guys.
