I get what you’re saying. But why on earth would he recommend I buy a COPPER algaecide for a vinyl Intex pool? That’s crazy talk! The bottle even says do not use in pools with vinyl liners. I don’t care about the Walmart remark lol! Like I said, it’s true. ?? The copper algaecide is what made me run for my life lolYou have to give the guy the benefit of the doubt. He probably meant no harm, but this is what Wal-Mart is famous for. We had an Intex Pool and quite honestly, did not care one bit about what people thought. No one is here to judge on what pools people own, etc. It was probably just conversation. Personally, I would have asked him what he meant by the statement, as I would be confused. And the copper bit, just sheer ignorance.
Pool store employee's know no better. There training is poor at the least.
Picture a mom and pop store with a few items on the shelf:
2) Baking Soda
4) Muriatic Acid
5) The TF-100 Test Kit + Speed Stir & Accessories
Incidentals that your pool could need (Hardware, that is). Now, remove all the magic potions that you really do not need, and one could operate a mom and pop store in a store front property that is 400 square feet. Now, walk into a Leslie's and you are talking 2,000-4,000 square feet. There is one in Freehold, NJ that is at least 4,000 square feet, with things you really do not need.
The testing may not be off by that much, but they always are recommending products that just are not needed. Take care and good luck!
