Chlorine tablets work perfectly
The chlorine pool tablets always work well. I have bought them several times and have had no problems. They are less expensive on Amazon, and arrive just when they say they will arrive.

Great price, Great product
Was surprised to see Amazon 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.

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.

Great but buy the right size!
High-quality, effective, but way too big for floating dispenser with 1.2 inch diameter. OK value for money since this is not a bulk package, durable, slow to dissolve, strong odor, great algae removal.
