      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.....

      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.

      Great products
      I have been using these products for years. The prices are fair and they work great that is why I keep buying my products from in the swim.

      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.

      Best general algacide
      I have used this product from ITS since the mid-1980s. My pool is a gunite (concrete) pool with an epoxy paint finish (no liner). I've had a salt cell system for a few years and my need for chemicals, other than salt, has dropped dramatically, but I still use Algacide 60+ in thee spring when opening the pool and during the summer if I see any algae at all (my robotic cleaner doesn't get in the corners real well) and I use 1 quart for winterizing. Great product. I've tried some others but have ... read more always come back to this one.

      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.

      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'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.

      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!

      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.

    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.
