    • Great option for winter chlorination when salt systems stop producing chlorine Great option for winter chlorination when salt systems stop producing chlorine

I primarily use these chlorine tablets during the winter months when my pool water temperature drops too low for my salt cell to generate chlorine. Once the water gets cold, my salt system stops producing chlorine, so I switch to using these tablets to maintain sanitation through the winter. I typically place one or two tablets in the skimmer basket and allow them to dissolve slowly. They work well for maintaining chlorine levels without needing to constantly add liquid chlorine. One thing I like is that the tablets come individually wrapped, which helps keep moisture out and makes them easy to store between seasons. Since I only use them during the colder months, one bucket lasts me several winter seasons. Pros: • slow dissolving tablets • individually wrapped for easy storage • good backup for saltwater pools in winter Cons: • tablets should be stored in a cool dry place If you have a saltwater pool, these are a great option to keep on hand for winter when the salt system shuts down. ... show more

Way cheaper than the store price. Tabs are individually wrapped which I don’t care for. Easier to load when they are not wrapped

    • Be careful opening bags
Style: Advanced Tablets Size: 5 lbs
HTH has great products, but open the bags with scissors. If you rip them open be prepared to inhale chlorine dust when it flys out.

Style: Advanced Tablets Size: 25 lbs
Quick shipping at a great price. 50 tabs in each container (I ordered x3) that were individually wrapped - so didn't ruin my clothes. Best of all was the price - much lower than our local stores. I have already encouraged friends and family to stock up from this store.
