      Incredible product!!
      I bought this a few weeks ago after trying everything else first. 2 days after using this product, not only was the algae completely eliminated but the water is clearer than it has ever been ! Highly recommended !!

      Fixed a problem
      We have struggled to keep our chlorine level up all summer. Despite little sign of black algaecide, we decided to try treating it anyway. Amazingly, our chlorine level is now staying at the recommended level and we hope our problem is solved.

      Finally--a product that worked!
      For some reason this summer, we got a huge outbreak of algae and nothing we had used in the past would break it up. We dosed the pool with this black algaecide and within one dose we had a cleared problem.

      Worked like a charm
      This spring the kids took the winter cover off without my help and got the filthy sludge from the cover in the pool, by the time I got it filled back up and everything back together a few days later we had a nice green mess in the pool, I knew it would take a fortune worth of chemicals to get it back, I even contemplated draining the whole pool and starting from scratch, but I saw this product and figured it was cheap enough to try. the next morning after putting it in the pool was cloudy and ... read more blue, a little claifier and a day or 2 later we were back in business. Worked great for me.

      AMAZING!!!!
      This product is amazing! We lived with a murky pool all last summer, and the pool store was telling us everything was fine. This year our pool was green when we opened it and after spending at least $400 on products from our local stores (yes, we used 2 different stores) we still had a murky pool that wouldn't stay balanced, and "silt" was constantly appearring. We were told we must need to replace our sand or our filter. We then ordered No Mor Problems and watched our pool fix itself before our ... read more eyes! Within 3 days we had a beautiful pool! Two months later, our water clarity is still brilliant! All we do is treat with this product weekly and add chlorine tabs. No more copper algeacide, super blue, shock! Give it a try!!! It's well worth it!!!

      8 years of perfect clarity
      I started using No Mor Problems 8 years ago in our 10,000 gallon above-ground pool and it has performed perfectly. I use 2 1/2 ounces once a week and NEVER have algae problems. The only two times I have had an algae bloom was when I skipped the once-weekly application. Each time about a week after the missed dosing, the pool became a murky green, but cleared up in a few days after starting treatment again. If you are consistent, this product is very affordable. Small, regular doses keep algae in ... read more check and the water is really sparkling clear.

      This is th e best stuff I have ever used I love it
      I love yellow out I will never buy anything else. This is the only stuff that you can just put it in and let it go. Last summer my pool had really green water ,I went to the pool place in my area they gave me $150.00 worth of pool stuff, they told me to put it in and it would be clear in 3 days. I did this and still a green pool. I got this yellow out put it in and in 8 hours my pool was clear, I can not say enough good things about this product.

      Easy to use
      This product is amazing, I put it in my pool for the first time and 2 days later it was crystal clear. I will continue using this product for regular maintenance.

      Finaly something that works
      We (or a friend) brought mustard algae from the lake. I spent hundreds of dollars on other chemicals in the past 3 years to get reed of the algae but it kept coming back a couple times per year, especially when we forgot to run the Polaris for a week. I tried every algaecide I could find in the stores and pool supplies companies. That's when I sent an email to ask what product would work best for my well water, salt system inground vinyl pool. Yellow out is just fantastic, It killed mustard ... read more algae overnight like nothing I tried before, with less than 2 pounds of it! Hopefully it is gone for good! Untill somebody brings some from the lake again. Tip: Make sure you ask anybody ready to swim in your pool if they used their bathing suit in a pond, lake, river, sea etc... and if they washed their suit since. That's how we ended up with mustard algae in the first place. Great product, Thanks.

      Best Results Ever
      I would like to say, we thought our Algae would never have been cleaned up with the well water we use for our 30,000 pool during spring opening. But this kit really did the job. I was VERY impressed. Within 1 week, our pool was crystal clear. I would definitely suggest this kit for bad algae problems, it works AWESOME!
    3. 10 years ago
      Wow Really works
      I couldn't get my pool clear after dumping tons of shock and algacide in it. I bought this package and it was clear within 4 day.

      Winterizing Wonders
      Third year now that I have used the In The Swim winterizing package for my in-ground pool. Works like a charm and saves the cost of hiring someone to do it for me. This spring, the water needed less attention than prior seasons due to addition of floating clorinator included in the package. Thanks for making opening easier but my former pool guy misses the business. Maybe he'll pay you not to sell your products ??

    Use Pool Algaecides for Clear Water
    Algae blooms cause problems for many swimming pool owners and pool algaecides can prevent this problem from happening. While lack of proper circulation and out-of-balance water chemistry can lead to the growth of algae in pools, even carefully maintained swimming pools can sometimes experience algae growth which is why it's important to employ pool algaecides whenever possible. This is because algae spores can be carried into the water by the wind and by swimmers. Once algae blooms take root in your pool, they can become unsightly and can clog your pool's filter. As a result, it's important to use effective pool algaecides as soon as an algae bloom appears in your pool, and it's also a good idea to take measures to prevent algae from growing in your pool in the first place by adding pool algaecides into your pool water initially. In the Swim's swimming pool algaecides are highly effective products which will help you keep your pool water crystal clear and algae-free. Our powerful pool algaecides reduce the need for pool shock treatments and are safe for a variety of pool surfaces. In addition, In the Swim's pool algaecides will effectively eradicate and prevent the growth of several different types of algae. Our swimming pool algaecides can take your pool from cloudy to crystal clear in less than 24 hours. In the Swim's selection of pool algaecides includes Green to Clean algaecide, which is a natural and non-toxic chlorine enhancer that boosts the killing power of chlorine-based shock products. We also offer Algaecide 60 Plus, a non-metallic and non-foaming algaecide for pools that is even effective against pink algae. Additional swimming pool algaecides available from In the Swim include Super Algaecide and Phos Free. Super Algaecide is a top-quality copper-based algaecide for pools that is ideal for spring openings while Phos Free eliminates phosphates from the water, thereby effectively starving the algae and preventing its growth. From our Green to Clean swimming pool algaecides to our Phos Free products, all of our available algaecides and algae-preventing formulas are powerful, effective and safe. Furthermore, all pool algaecides from In the Swim are available for great value so you can take care of your pool and enjoy sparkling clear water without straining your budget.
