      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.

      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!

      Economical, but . . .
      I purchased this in part because the recommended dosage makes it economical. Using the proper initial dose and maintenance doses, and an extra maintenance dose after a rain, I noticed green algae growth after about two weeks. Another initial dose, another maintenance dose, an an extra maintenance dose after more rain and I am seeing new algae (again after about two more weeks). I am going to increase the rate of maintenance doses and see what happens. Basically, I'm happy, but I think the ... read more recommended dosage is a little light. When applied, the algaecide is cloudy, but clears quickly. I use conventional chlorine based pool chemistry.

      Algaecide 50 - Great Stuff
      I have been using "In The Swim" chemicals (Including Algaecide 50) to open and close my pool for (4) years now. Never a problem. I have friends that have to empty better than half the water each spring just to clean and get their pool ready. I have never had to drain any water. "Closing" and more importantly "opening" has always been flawless. I will continue using Algaecide 50 as well as all the other "In The Swim" chemicals. GREAT STUFF!

      works great
      I have never had an easier pool season. I have tried other brands and they just didnt accomplish the job. But if you have blond hair, be careful when swimming right after adding the product

      Good product!
      I got this product for the 4th of July weekend pool party. Worked wonderful. Have not added anything to the pool in over two weeks and the water is still clear and blue. Will order more soon.

      The BEST algaecide ever!
      I started using this product about 5 years ago to get rid of a huge algae bloom. Nothing had worked up until then. The SeaKlear was nothing short of amazing. I use 1/2 a bottle every 3 months along with In the Swim super shock and I have the clearest water all the time.

    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.
