They said it was because I am using bleach for the pool and it would cause the o-rings and gaskets to deteriorate quicker.
Well, that makes sense, doesn't it?
I'm sure they would like for you to switch to 3" tablets because they don't....uhhhh, well never mind, they have the same thing in them as the bleach so that won't work.
So, let's go ahead and switch to powdered.....X!!$%&?!! Doggonit! same thing as bleach, again!!
Oh, I got it now, they want you to switch to a Salt water generator so your gaskets will be safe and sound and won't have to get eaten up by that nasty Chlor...... Holy Benoli! No matter what they want you to use, they all contain EXACTLY what's in bleach...CHLORINE!! Well, I'll be!!
BBB teaches you to understand pool water chemisty, and through careful testing and knowing what to do with the results, allows you to rid yourself of pool stores that, while perhaps well intentioned, simply waste your money.
