I did look at the pool caculator site recommended and it was saved to favs, very nice site
heres my issue, on the pool caculator site i put a 10k gallon pool as reference and used 16oz of 65% cal hypo and it approx raised FC to 7.7, so that would be almost the same as 1 gallon of 7.7% bleach. Thats the way im seeing it. please correct me if im wrong im just trying to find the best and most earth friendly method of boosting FC. (Less waste/garbage using 1lb shock bags vs 3 to 4 jugs of bleach)

I have found LC at 10% in bulk 15 gallon jugs but its 1 hr away and only open of course when im working also.

Also looking at waterbears results it was listed that 1lb of 65% cal-hypo raises 1000 gallons to approx 7.5.
That would mean that adding that same one lb bag to 10k gallons of water would barley even raise the FC above 1ppm.
I like to use the 10k water ammount since its easier and we all use this for bleach caculations also, so its good to compare side by side.

Ive read lots of posts this year and know the ups/downs and other effects of cal-hypo and bleach and so on. Its good to know your options so you can make a good decision on what works best for your application. thanks again
