So when I first stumbled on this site a couple of weeks ago - I went for the Walmart bleach isle and subsequently figured out that either:
1 - the total volume of my pool must be slightly more than the pool calculator was suggesting; or
2 - Walmart's claimed 6% chlorine level in bleach is not quite what it should be.
I've now found a slightly cheaper (9 cents per 1.4 gallon) option - and it's name brand (chlorox). I went to dose based on the pool calculator and the net increase in FC levels were quite substantially higher.
Now granted, pool conditions are obviously not lab conditions, but I did notice a more yellow tinge and I couldn't help but notice a FC level that went higher and stayed higher... One would assume that if the label says 6% there would be relatively strict controls on that. But based on my experiences with Walmart from a supplier perspective I can't help but think that perhaps the suppliers being squeezed so hard would resort to slight dilution of the product.
Has anyone noticed anything similar?
