      Very good product
      Used this on my very dirty Sta-Rite cartridge filter and it did a great job cleaning it up. Soaked it over night and it did a fantastic job.

      Great filter cleaner!
      I purchases this filter cleaner for pool closing. In the past, I only used vinegar water to clean my DE filter screens. They had years of build up stains on them. I called and received the MSDS for this product to make sure there were no phosphates that might harm the pool next year or anything that might harm the grass as I was dumping the barrel of water out on the lawn. Everything was safe and the screens look great. There was some black stains from the o ring that remained but after 26 ... read more years, my screens are ready for another year.

      I used this product last summer and had the least pool maintenance in 30 years. My pool water remained clean and shiny throughout the summer.

      Algae Pool Pack
      We bought this last month when we had an algae bloom. The package arrived very fast and we added it to the pool, following the directions. It cut the algae out in no time at all and was just what we needed.

      Made for specific problem and worked like a charm
      In The Swim once again makes life so much easier. They boxed everything we need into 1 package for fighting the Green Algae problem we had. We emptied the In-The-Swim product into our pool in the late evening and the next morning all the Green Algae was gone. It's been 2 weeks and we've had many rain falls (which contributes to algae) and still our pool is crystal clean. Thanks In-The-Swim for putting all the products together for a great price and easy use.

      Great product
      I live in the Deep South , so not much concern about freezing, but this kit does a great job of keeping the pool algae and stain free. It’s my third year of using this, and each time I open the pool it’s just as good as when I closed it. I will continue to use this product and highly recommend.

      "Great products for pool people at a Great Price"!
      I have been using this kit for years. Follow the directions, and when opening the pool in the spring, it looks as clear as it did when I closed it for the winter. Have never had a bad experience with any products that I purchase from In The Swim. Come to think of it, I buy all my pool products from In The Swim. Thank you for the service you provide and that includes customer service. Kudos !!!

      Worked great for a gender reveal!
      We used this to tint the water in a fire engine to use in a baby gender reveal party. This was a big hit and worked great.

      Best Chemicals and Value Ever!
      I used these chemicals last Summer! Wow!! They're Awsome! I opened the pool on Saturday, and it was crystal clear by Monday. That's NEVER happened with ANY of our pools over the years. I've always used HTH. Mostly because it was economical. Well, I'd spend Hundreds to keep the pool clean. With the In-The-Swim Brand, my pool was the only one in the neighborhood that wasn't pea soup last summer. I used less chemicals. I spent half the money I usually spend, and there was little to no work to keep ... read more the pool clean! This brand is incredible. I'd recommend it to everyone! I'm just sorry I hadn't found it sooner. I'll be forever loyal. Besides, it comes to my house with FREE SHIPPING! What else could a Housewife ask for? Great Product. you won't be sorry.

      Great Buy!
      I bought this product in the spring, the summer is now half over and looks like it is definitely going to last. Everyone always used to tell me chemicals were expensive for a pool but at this price.... I don't think anyone can complain!

      Great Product, Great Price & Fast Delivery
      Pool chemicals always feel like a chore to purchase locally, because they can be VERY expensive. When I saw that In The Swim had a Chemical Value Kit, I jumped on it. It comes with almost everything you need to run your pool and the best part is "IT WAS CHEAP." The quality of the product was amazing and everything was foolproof. I didn't have to measure anything out, because it was all pre-measured. Not too mention, the shipping was EXTREMELY fast. I am now a customer FOR LIFE!!
