HTH 42052W, Pool Care 3" Chlorine Tabs Advanced, 5 lbs

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.

Last a week in my pool. Keeps it nice and clean. These will be my go to

Perfect for controlling pool water systems. Drop into pool floaters and forget it. Great value. Easy to handle.

We have been using this chlorine for 3 years. One of these boxes lasts all summer so we buy one each year. We have a 15 ft round pool about 4 ft deep maybe 4.5.. one tablet at a time, usually put a new one in while the one in there looks like a ritz cracker LOL

I will say I usually dont buy this brand but in a pinch they worked great. Its a chlorine tablet, it does what its supposed to do. Ok for the money.

Works better than clorox. I’ve been way happier with this product and would recommend to anyone looking for an alternative that’s a better price. Our pool has been on point since buying this brand.

I like the HTH brand and feel that their products are slightly less expensive then other brands and do the same thing. I also like the fact that they don't wrap each tablet in an individual plastic wrapper. They dissolve easily and do the job

This is the best product in the market to keep your pool water crystal clear. We have a 15' Intex above ground pool with a sand filter and we don't need to put any effort in keeping the water completely clear. It helps with algae formation and other imbalance of the water. It's the only tablet you need. We have used the Clorox brand and other brands and this one is the best. This is in Puerto Rico where you have hot weather year round and a lot of rain during the months of August through October and we still have no problem with the clarity of our pool water. The only strong smell is while removing the tablet from the container, but once it's in the floater you're unable to smell it. Ph and everything else stays within balance. I have purchased it twice Amazon before and other times at Walmart. For some reason Amazon stopped carrying the product and/or shipping it to Puerto Rico. Walmart in PR stopped carrying it. I was thrilled to find it on Amazon again. Only two tablets were broken and, that's no problem. You can still use them like that in your floater. There's absolutely no leakage from the container. The tablet lasts about a week to a week and a half. Hopefully, I can continue to buy them on Amazon. Shipping was super fast. I highly recommend this product! A++++
