      AMAZING
      Returned from a vacation to find the pool had a bad case of green algae. Used this product for the first time and was very pleased with the ease of use and results. Did not make the water sparkling clean but sure made it easier to get the algae under control.

      Does exactly what it says!!
      Bought this product while looking to buy a pool cover. My pool looked like a green swamp after a long period of rain and warm weather. Needless to say that I'm a firm believer in the saying that anything to good to be true usually is. All I have to say is WOW!! This stuff is fantastic. Poured the product around the edge of the pool and in 2 days water was crystal clear. No scrubbing needed.Worked so well I immediately ordered another container! Get this, you won't be disappointed!!

      Best Algaecide on the market
      We have used this product for at least 8 years straight now and no other product works as efficiently as this. It is costly but no other products are needed as others that need an additional product to eliminate the foam.

      Algae Clear
      With the ugly weather we had this summer and turning cold overnight my pool was a mess. This product helped turn my pool back to the clear inviting pool it should be. Very effective and worth every penny.

      Great Product - Needed more shock
      The Algae Attack Pool Chemical Value Pack was fantastic. It was able to kill the algae in our pool. We just bought a house that came with a pool. The previous owners didn't take care of the pool so it was EXTREMELY DARK GREEN! This product worked great in getting it clean! (It didn't get the pool 100% clean, but it was so horrible.) Definitely recommend the product! Our gunite pool has never been happier!

      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.

      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.

      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!!!

      It works well!
      Have used this in the past and it works well enough to purchase again. It devastates any returning black algae. I had it speckled all over when I went to open my pool 2 years ago. Nothing worked till this. I did scrub all over once I put it in the first time. The algae let go and was swept up and away.

      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.

      This is the Holy Grail of Algaecides
      I had terrible problems with black algae spots that could not be killed by any other products. They resisted brushing, and even pressure washing in my drained pool. Upon re-filling my pool, the black algae came back to life. I found this product, added it to my pool according to directions, and it quickly killed the black algae once and for all. I now use this product to prevent any algae growth in my pool.

      BEST PRODUCT!!!!!!!!!!!!!!!!!!!!!!
      LAST WINTER I PUT A SOLAR COVER ON MY POOL, AS THE WINTER IS RELATIVELY MILD HERE. WHEN THAT COVER CAME OFF, MY POOL WAS SO GREEN IT LOOKED LIKE A LOUISIANA SWAMP! I WAS SOMEWHAT CONCERNED ON A CLEAN, CLEAR FUTURE FOR MY POOL. THE YELLOW OUT IS AN ALGAE PROBLEM SOLVER... AN UNDERSTATEMENT.. I USED IT WITH CHLORINE AND MY IN THE SWIM SHOCK. IT WAS INCREDIBLE JUST HOW GREAT THIS PRODUCT IS! FROM SWAMP TO CRYSTAL CLEAR! I'M SOLD. I WILL USE YELLOW OUT ALWAYS! IT WILL NOT LET YOU DOWN.

      Amazing Product
      I used 4 lbs of Yellow Out and 4 lbs of shock and it changed my pool water from green to clear blue. This is the best product I have ever used for getting rid of algae. Don't bother with going to a pool store and buying expensive chemicals. Just follow the instructions on Yellow Out and it will give you something to shout about. My pool look better than it has in years. I am thankful i found this product and will keep some on hand.

    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.
