I sat in on a local "pool school" with a friend who just put up a pool, and the pool store started him on the Mineral Springs product. I told him about BBB, and he told me to come with him to Pool school to learn about Mineral Springs. When the Rep would get to a point to take questions about each product like Mineral Springs beginnings, or renewal, or other product...I would raise my hand and say, "but isn't that just basically chlorine whether is Sodium Hypochlorite, or Dyclor or Tri chlor....he was pretty dumbfounded, and said...UH...WELL..YES, BUT our product also has essential stabilizers, minerals and conditioners......and I was like..oh you mean like Cyanuric Acid which you can buy separately, or you mentioned water buffers, do you mean like Sodium Bicarbonate..and the guy says YES...and I said...well that is simply baking soda right? and again he was tripping over his own tongue trying to come up with an answer as to why Mineral Springs was better. So did I convince anyone, over the slick salesman pitch? probably not..but I do know there were LOTS of people asking questions if what I was saying was true, and they could really treat there own pool with simple chlorine bleach, baking soda and borax...as opposed to the $15.00 a week Mineral Springs additives.
