      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.

      Actually Works as Described
      Have had a recurring problem with mustard algae. Switched to this product and problem has disappeared. Just follow the directions.

      Did Not Like
      I decided to try this algaecide since it was less expensive than Algaecide 60+. The foaming was minimal but it seemed to leave a sticky black substance/film on my skimmer and basket. Thought I was using too much but that wasn't the case so will buy Algaecide 60+ from now on.

      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.

      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 ??

      Winter Algaecide
      I have been using the In the swim winter algaecide for about 12 years.... Works great... I put one quart in at closing and I add a quart about ten day before I open the pool in the spring.....

      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.

      SImply works
      Was told by someone 2 years ago I don't need algaecide and ever since had nothing but problems. Started this year and decided to try this out since I had yellow algae problems. One day after first treatment the algae was gone and my pool has never been more clear. I put a small amount in once a week and thus far have been algae free.

      Best on market
      We have had 18 x 34 aboveground pool for 27 years and I've used this product for years combined with in the swim 3" chlorine tablets. We use nothing else besides liquid shock on occasion and our pool is crystal clear all the time with very little maintenance required. An added benefit is this is nonmetallic and does not turn blonde hair green.

      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!

      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.
