Last yr (our first year w/ 27'AG pool) when I was following advice here and using generic clorox ultra, the local family run pool store owner gave me the scenario of liquid shock vs ultra clorox. I don't remember the specifics, but the shock was at least equal in price after you make the percentages equal, but needing much less of it thus less hassle, carrying heavy bottles from store, and less landfill. Am I missing something of why this is not the preferred method? Is there ever a benefit to using granules? I tried a few times because they're not supposed to be used up as quickly, but there was always white stuff all over the bottom of the pool and I hate to bleach the liner.
Thanks.
