      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.....

      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 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.

      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.

      Wonderful Algaecide!
      18x36 in ground. Water murky, thick and visible green algae begining to show on steps: Time to close pool so used one whole bottle and expected to have to vacuum out a mess. The next morning the pool was crystal clear and no dead grey algae to vaccum out so I didn't. I threw in 5 lbs of super shock and closed her up. I love this algaecide!!!Will order more for opening next pool season!Oh yeah was here two days after I put in the order and no shipping fee just a handling fee

      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.

      WORKS GREAT
      I USE ALGAECIDE ALL THE TIME..AS A WEEKLY MAINTENCE AND AT THE BEGINNING OF THE SEASON...I WOULD RECOMMEND THIS PRODUCT TO ALL. I HAVE HAD GOOD LUCK USING THE ALGAECIDE EVERY YEAR AND MY POOL IS AS CRYSTAL CLEAR FROM THE TIME OF OPENING TO CLOSING. I ALWAYS HAVE AN EXTRA ONE ON HAND IN CASE OF BAD WEATHER..

      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.

      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.

      cheaper by the 1/2 gal
      I prefer the Algecide 60 plus over all the others. It doesn't foam and it is powerful enough. I do not advise algecide with copper. One problem is that one of the containers had been opened and was missing its seal. So, there was some leakage into the shipping box.

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

      The best!
      This is our favorite for algacides! No more chemical reaction from the copper used in most algaecides which means no green hair...Yay! Very concentrated so it last a long 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.
