    Pool Algaecides

    1. 3 years ago
      Works Great!
      I have bought other brands and higher priced algaecides for the pool and none of them work as effectively as this product. I buy the 1/2 gallon sizes so that I do not run out and use this exclusively for almost algae free swimming seasons.

      Algaecide That Works!
      We were fighting a losing battle with algae in our pool. We tried many recommended brand name products, but couldn't get it under control. Then we tried 'In The Swim Algaecide' and our pool was crystal clear in no time. It's so easy to use - no mixing or measuring - just pour straight from the bottle around the perimeter of the pool. You'll see a huge improvement the same day.

      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.

      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.

      Beat pool season ever
      This is the best pool season in regards to maintenance in years. I was trying to decide on an algaecide this year and selected this based on the ingredients and something i had read on another pool care site.... we've had our pool for 16 years and started with chlorine, switched to baquacil for several years, back to chlorine...... out of the 16 years we probably had 2 trouble free years.... until this year.......i bought 24 pk of shock and this algaecide (i usually go through tons of shock and ... read more a few bottles of algaecide trying to keep the algae killed and "trying" to have clear water).... We have a 24' above ground and don't cover it over the winter... we continue to scoop fallen leaves out until the end of fall. In April we had a few nice days so i scooped out most of the remainder of the leaves and mixed 2 bags of shock in a bucket of water and dumped in the pool to get a jump start (before filter). Upon actually opening the pool the middle of May (connecting the filter) i added another bag of shock and filled our floating chlorine dispenser with four 3" chlorine tablets and added probably 6 ounces of the algaecide. I have not used any shock since.. I have used this algaecide faithfully every sunday and have not seen one bit of algae all year. Our pool water is so clean, clear and sparkling.... we usually fight cloudiness, algae etc. I replace the tablets when gone add the algaecide once a week and this has been the extent of my maintenance this year. I actually love our pool again. I will not open the pool again without this algaecide... I even bought two of the sparkle cubes this year as i used one last year and it seemed to help but still had a few algae blooms... i haven't even opened a sparkle cube yet...... i am very happy with this product.

      great product
      This algecide is better than any other product I have used in our pool. Having a 15 year old concrete pool sometimes algae becomes a problem due to the rough insides of the pool. Applying this algecide is easy, just pour it around the edge of pool. Sweep algae off edges of pool and it is gone with in a day or 2. Better priced product than same kind at pool stores.

      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 ??

      Algae Problem??? NO PROBLEM!!!
      Been having horrible algae problems for the last two seasons. Tried everything - algaecide, super shock... NOTHING worked. Saw this product, and thought "what the heck...it's worth a shot." OMG ~ so glad I did. Liner is squeaky clean...haven't had that for three seasons! Highly recommend this product. It's been a sanity saver, and we're FINALLY enjoying the pool again.

      The best, non-copper Algecide.
      This is the only Algaecide I buy or would recommend to a friend. First, it has NO copper. Copper is the traditional old-school algaecide and what is in the cheap pool store blue stuff. Now Copper does work very well as algae hates copper, BUT copper will build up over time and eventually react with your chlorine giving you the dreaded GREEN HAIR. Yes, green hair is caused by excess copper, not chlorine as the urban legend goes. This algaecide is copper free and non-foaming. It works ... read more exceptionally well and won't make you look like you work in the Emerald City.

      No More Algae-EVER with this product
      This product is AMAZING. I have used this product for 2 years now. I use it weekly during the swim season and use it to close our pool in the fall. I pour an entire bottle in when we close the pool and I have yet to have any algea when we open in the spring. My dogs quite often swim in our nasty pond and then swim in the pool. Not once have they transferred the algea to the pool. EXCELLENT PRODUCT.

      Excellent on algae prevention
      This is a very effective algaecide. It does not matter what the ph level of our pool water is, it does an excellet job killing all types of algae that is common to pools. We have used this product for several years and have the best luck of any product we have ever used. We highly recommend this product for your pool. We love it, and continue to use it!

    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.
