What is the worst "pool store" info you have heard?

[matt4x4]

There was a woman in the local highend ritzy poolstore, I was in getting some feherguard clips for my reel, this woman had a shopping cart full of stuff, I asked her why she had all this stuff (I think it was hundreds of $ worth), she showed me her water sample printout and their recommendations.
I told her to put the stuff back, go to walmart and get the 3 B's as well, I pointed her to this forum, don't know if she ever signed up here, but she left without dropping a cent - and i don't feel bad about it!
I've stopped many from making that recommended purchase, converted about 20 people at work to the 3b's, and almost all my neighbours, so the moral is that together we can stop the poolstore madness!!!

Anybody remember The Rockford Files?

There was an episode where a scam corp. is selling phony retirement homes in the desert and have a lake as part of the plan. Rockford finds an old scam artist acquaintance working as a salesman who says to him: "but Jim, I didn't invent pigeons!"

Later Rockford sends his father to be a buyer and he comes back and says "And there we were, in the middle of desert, nothing but sand and cactus, and this feller tried to sell me a boat!"

Don't be a pool store pigeon!

The clerk at my local pool store tested the water and said that my Ca hardness was worryingly high. His test showed 300 and it's a plaster pool so I'm not too worried about it. Then he sent me home with a Cal Hypo shock to clear up the CC. I had already dumped it in the pool when I realized that I was adding yet more calcium to the pool at the suggestion of the guy who had just told me I had too much calcium! I suppose that makes me a fools accomplice.
