These chlorinating granules are terrible.  Nowhere in the description does it mention that this is "Sodium Dichloro-s-Triazinetrione Hydrated".  It is very ineffective in getting rid of the green color from algae.  And it contains a high amount of cyanuric acid (pool stabilizer).  When this builds up, the chlorine becomes less effective, and more has to be added, which adds even more cyanuric acid.  And the vicious circle continues.  Calcium Hypochlorite is the best chlorine granules.  I would not have bought this had I known what it is.  I did return it.

Terrible and ineffective chlorine.

This is a Walmart/Sams product.  Last year, 50 lbs. sold at Sams Club for this same price.  This year, the club sells 40 lbs for the same price.  Obviously, this product from Walmart--at 50 lbs-- is less expensive per pound, and as a multi-year user, I'm always satisfied that it works.
