      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.

      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.

      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!

      Green To Clean FAST!
      Due to a hurricane and alot of rain our pool was left with alot of debris, and with the hot , humid temperatures we had a major algae bloom within a couple of days. By the time we got power back the pool was green from top to bottom. I had ordered this product with my usual order of chlorine just to have on hand. Within a little over a day we had our pool back to normal. I really did not think it would clear it that fast, but it did. It is part of my pool staples now every year. And the price is ... read more excellent compared to a walk-in store.

      Wonderful !!
      Our pool was dark green with a layer of scum on top. We worked hard to get it clean to no avail. I was ready to give up and drain it . I ordered this product as a one last ditch effort . The first treatment didn’t work , the next day we put the rest of it in and by the next morning , the green was gone !! I couldn’t believe it when my husband called me out to look at it ! This product really works and now we are enjoying our pool= green free !!

      most copper content
      still have black algae problems and have done everything recommended. Product seemed to slow things a bit but didn't kill it off.I steel brushed it then scrubbed with a chlorine tab then shocked and then added 15 oz of this product at night, only to have the algae resurface 4 days later.

      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.

      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.

      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.

      No Mor Money
      The recommended dosage is quite costly to keep up with and will require you to go thru several bottles in a season. It's active ingredient: ~40% sodium bromide...not sure why they can't tell you that in the specs, other than it's not all that special. I ran into problems with this stuff - the bottle doesn't really address if you have algae - I had to resort to a quat to take care of the problem. So, if you have a perfect pool and never get algae, this is for you. But I would highly recommend ... read more using a quat or copper-based algaecide in addition to or instead of this product. This is not the panacea it (and most reviewers) claim it to be!

      Great fixer for major algae problems
      Pool has been having major algae problems and has been cloudy. No matter how much algaecide, chlorine, and clarifier I use the pool is still cloudy and not sparkling blue. One application of this immediately fix the issue the next day. I only need to use this twice a year duting the summer season with bi-weekly shocking of the pool and had no more problems as the name implies.

      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.

      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.

      Worked fast
      I had a few patches of yellow algae on the plaster walls of my pool that other algaecides never quite got rid of. I brushed the affected areas, added Yellow Out and did a chlorine shock. The walls and water looked great the next morning! I was surprised the chlorine went from 10 ppm to 0 ppm overnight, but I just added a few more pounds of chlorine and now it is stable 2 ppm. The algae has not come back for two weeks! If it stays away two more, I will definitely buy Yellow Out again.

      Really works on yellow algae!
      I have a 22,000 gallon pool, and my pool man told me to use 8 pounds of Yellow Out. I had been fighting my green pool for almost three weeks, adding hundreds of dollars of chemicals and running the pool continuously. Then, I added the Yellow Out by scoops, following each scoop with a scoop of chlorine. The next morning my pool was blue. I still needed to add clarifier to eliminate a little cloudiness, but what a relief!

      Eliminated My Yellow Algae
      We have a 15,000 gallon 16 year old concrete pool that needs to be refinished because it has corroded over the years from chemical use which creates the perfect environment for algae growth. We had mustard algea pretty much everywhere with a concentration on the sides and steps. The Super Algeacide and Super Shock totally eliminated it! It took a lot of elbow grease (brushing and vacuuming), but after a couple days and almost the entire bottle of Super Algeacide over the course of thee days, it ... read more is gone and has remained gone! Last summer I spent much more $ at our local pool supply store buying products to eliminate the mustard algea. Great product and great price!

    In The Swim Knowledge Pool: Algaecides

    In The Swim's Dr. Pool

    Why Use Pool Algaecides?

    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. It is important to use an effective treatment 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.


    For killing out of control algae blooms, look to Green to Clean and Yellow Out, natural and non-toxic chlorine enhancers that boost the killing power of chlorine pool shock. Small localized areas of algae can be eradicated with In The Swim Pool Algaecide, Algaecide 50 and Algaecide 60 Plus, and a stiff pool brush. For repeated algae blooms, step up protection with our Super Algaecide, No Mor Problems or Algae Clear for stubborn situations.


    Preventing Pool Algae

    •  1. Well balanced water, with proper pH, Alkalinity, Calcium Hardness and Stabilizer levels.
    •  2. Constant and consistent chlorine level of 1-3 ppm, along with regular superchlorination to 10+ ppm.
    •  3. An effective filter; run the pump each day for 12 hours daily, more or less, depending on effectiveness.
    •  4. A clean pool; brush, skim and vacuum to remove organic debris which contributes to algae problems.
    •  5. Monitor levels of phospates in the pool. Use a phosphate remover when levels exceed 300 ppb.

    If you do all of that, and still have algae - begin an algaecide treatment with weekly doses of our Pool AlgaecideAlgaecide 50 or Algaecide 60 Plus, to assist your chlorine to combat pool algae. Algaecides accomplish this by eroding the outer protective layers of the organism, allowing chlorine to penetrate into the cells.


    Killing Pool Algae

    •  1. Clean pool of debris with skimming, vacuuming and brushing pool.
    •  2. Adjust Alkalinity to 80-120 ppm, Calcium Hardness to 180+ ppm, pH to 7.2-7.3, and stabilizer to 20-50 ppm. 
    •  3. Add Pool Shock per label instructions.
      • - For light green algae with good visibility, add 1-2 lbs of shock per 10,000 gallons.
      • - For medium green pools with visible shallow end floor, add 2-3 lbs shock per 10,000 gallons.
      • - For dark green pools with very poor visibility, use Swamp Treat or Green to Clean with a triple-dose shock.
    •  4. Brush pool and run filter overnight (remove solar blanket covers while chlorine levels are high).
    •  5. In 12 hrs, check pH and chlorine levels. If chlorine has dropped to near zero, repeat treatment.
    •  6. Continue to run filter 24/7, cleaning filter only when filter pressure rises or flow rates decrease.
    •  7. Add a Clarifier after 2-3 days, to assist your filter in removing suspended particles.
    •  8. Add an Algaecide after 4-5 days, adding an initial dosage, followed by regular maintenance doses, per label. 
    •  9. Add a Filter Cleaner after 5-7 days, to remove algae particles trapped inside of sand or cartridge pool filters.
