Will not disappoint!

This a great product and I do recommend it. The container itself has many great features. First, the container is fantastic. It's a tub with an open/close lid that protects the product and seals in the chemical smells of chlorine. We've been using this product for six months without any issues. It dissolves properly in the chlorine dispenser and doesn't produce algae.

Ten tabs per container

There are TEN (10) 3 inch tablets in container I received. Nobody thought that was Important to put on the Made in China label. These work with the Large model pool floating dispensers. No issue with product. They are NOT individually Wrapped items so expect some breakage during shipping. You can compare prices against the HTH 2 pk, not sure what those cost. They usually last a week. Good to Go so far

HTH Advanced works! Keeps pool clean and clear.

I bought the 25 pound HTH Advanced 3" tabs because it was best value for money and it was time to give a different brand a try. Ordered online and picked up in store. The name brand that I had used for previous 4 years did not keep my pool clean, clear, nor free of algae even though it had algaecide and chlorine in tabs. I had constant problems with that brand and spent a lot of money and time trying to keep pool clear and chlorine level up. Anyhow, I've been using the HTH Advanced for 2 months now. I am very pleased with HTH Advanced as it has kept pool clear and free of algae, even in the 100 degree humid weather we've had for past few weeks. Chlorine level is where it's supposed to be. I use 2 chlorine tablet floats in 18'x52" pool, one is half closed at bottom. I only need to refill floats every 7 to 10 days depending on weather and pool use.
