Calculations with 'end of season best prices' are as follows:
Cal-hypo (70%) granules are 55$ for 18 kg or 3$/kg. Correcting for 70% (100/70 x 3$/ kg) = 4.36$/kg.
Liquid chlorine bleach is 5.99$ for a 5 L jug at 10.8%, which works out to (108/1000 x 5 = 0.540 kg/6$) =11$/kg. So, since liquid chlorine bleach does not require a solids dissolution, it is great at startup, but cal-hypo is more economical for routine use in balanced seasonal pools.
