Review: Great price, Great product - Was surprised to see desertcart had the cheapest price on these. They keep the water clean and dissolve at a good rate. They work great! Pair with Clorox pool tester steps to stay on top of chemical levels! There were a few chipped/broken tabs in the box, but nothing too bad.
Review: Works Perfect - Love this product. Works perfect. It keeps your pool water completely clear. It is a shame that they won't ship it to Puerto Rico anymore.
