      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.

      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!

      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

    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.
