    Pool Algaecides

    1. 1 decade ago
      Finally--a product that worked!
      For some reason this summer, we got a huge outbreak of algae and nothing we had used in the past would break it up. We dosed the pool with this black algaecide and within one dose we had a cleared problem.

      most copper content
      still have black algae problems and have done everything recommended. Product seemed to slow things a bit but didn't kill it off.I steel brushed it then scrubbed with a chlorine tab then shocked and then added 15 oz of this product at night, only to have the algae resurface 4 days later.

      Black Algaecide

      PhosFree Believer
      9 year user. Got first sample from my pool builder. I hate the dangerous chemicals in algaecides, and don't like the foamy water, algaecide taste or water ring from dead algae. Open pool with shock & algaecide. Vaccuum and clean the waste. Balance pH, test phosphate. Use phosfree if elevated, then weekly phosfree + pool perfect. Keeps water sparkling with no foam, no water ring and no algae, even through August. Will occaisonally add a dose for unusually hot weather or a lot of rain. (I don't ... read more find the spring / fall treatment to be useful. Even with use at recommended dose, still need algaecide to open.)

      WOW - Best Purchase Ever
      I bought this product hoping to better manage my potential algae problem during the summer when on vacation. Sometimes my husband forgets to check the chemicals if I'm out of town and I would get to come back to an almost green pool. Now it's simple, a few capfuls in the skimmer before leaving and I come back to a worry free pool. I haven't had ANY algae problems even with the solar discs on and leaves in the pool! Simply amazing!!!

      best product, best deal
      It is now a known fact that algae cannot survive without phosphates, and Phos-Free easily brings your pool's phosphate level to zero. Since using this, I have never had even a hint of algae (and it was a significant fight before then). Plus, the 3 liter bottle from In The Swim costs about the same as what my local store charges for a 2 liter bottle. I usually get 2 bottles (which meets the free shipping level) and I'm good for the season. Not only that but a free test kit is included so you know ... read more it's working. All around, my favorite item from In The Swim.

      Wonderful, wonderful, wonderful!
      This is a wonderful product. Pool was starting to turn green. Children had tried to sweep green algae from bottom but could not get it off. Just one bottle for the size of our pool and the next day was was sparking blue again! This is a wonderful product, high recommend to all!!

      awesome product
      spent 100.00s of dollars trying to clean pool. our pool was cloudy and green for a month. nothing worked from pool store. looked online and found this. put this in at night next morning pool was blue and clear.I will never be without this product.

      Seems to work
      We were having trouble cleaning up our pool after a too-late spring opening. We tried a Green to Clean treatment, and the pool cleared up much more quickly. How much of this is due to the product, and how much to the associated shock treatment is hard to say, but if I ever find myself in the same predicament, I'll use the product again.

      BEST PRODUCT!!!!!!!!!!!!!!!!!!!!!!
      LAST WINTER I PUT A SOLAR COVER ON MY POOL, AS THE WINTER IS RELATIVELY MILD HERE. WHEN THAT COVER CAME OFF, MY POOL WAS SO GREEN IT LOOKED LIKE A LOUISIANA SWAMP! I WAS SOMEWHAT CONCERNED ON A CLEAN, CLEAR FUTURE FOR MY POOL. THE YELLOW OUT IS AN ALGAE PROBLEM SOLVER... AN UNDERSTATEMENT.. I USED IT WITH CHLORINE AND MY IN THE SWIM SHOCK. IT WAS INCREDIBLE JUST HOW GREAT THIS PRODUCT IS! FROM SWAMP TO CRYSTAL CLEAR! I'M SOLD. I WILL USE YELLOW OUT ALWAYS! IT WILL NOT LET YOU DOWN.

      Really works on yellow algae!
      I have a 22,000 gallon pool, and my pool man told me to use 8 pounds of Yellow Out. I had been fighting my green pool for almost three weeks, adding hundreds of dollars of chemicals and running the pool continuously. Then, I added the Yellow Out by scoops, following each scoop with a scoop of chlorine. The next morning my pool was blue. I still needed to add clarifier to eliminate a little cloudiness, but what a relief!

      Works like a charm
      The pools in my neighborhood, including mine, are afflicted with mustard algae. Yellow Out works overnight and leaves the water sparkling. A couple of weeks ago I had a "mustard algae emergency" and the closest pool store only sold a much more expensive product - I used it out of desperation and it clouded the water, I had to use two doses of it, it shot my chlorine into the "red" zone (which has never happened before), and I had to buy another product with enzymes to eat the stuff the other ... read more product didn't, and it took a week to uncloud my water. I spent over $75 in chemicals on this fiasco. $17 on Yellow Out and problem solved. I'm stocking up.

      Seems to work
      Due to lots of rain and water temperatures around 95, we were getting heavy algae requiring frequent cleaning and diatomaceous filter changes. After through cleaning and shocking I used the recommended amount of algaecide and after 10 days no algae or filter changes. HOWEVER, the water is no longer crystal clear; it has a yellowish tint.

      Incredible product!!
      I bought this a few weeks ago after trying everything else first. 2 days after using this product, not only was the algae completely eliminated but the water is clearer than it has ever been ! Highly recommended !!

      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.

      It Really Works
      I have had a real problem with Green Algae. My pool is exposed to direct sunlight all day. After several treatments of Shock and Algaecide. This product along with periodic shock treatment has kept it under control and looking great. All my pool chemicals and equipment are from In-The-Swim. They have the best prices and you can depend on fast delivery.

      worth it's weight in gold
      Honestly, this product is amazing. it's like a pool miracle. Last year I worked at for a pool builder, and had an opportunity to meet one of the reps from United Chemical, makers of No Mor Problems. My pool was literally a swamp when we opened it last year, I mean, really , we fished a dead squirrel out of there because the cover collapsed. I asked him what to do. He had me use their algaecide "black treat" the nuclear bomb of algeacides, then after the scrubbing /vacc'ing, backwashing etc, ... read more added the no mor problems- clear water. shock load lowered to practically zero- i didn't even use up a whole case of shock over the whole season. the pool was sparkling clean, stable and stain free. USE IT!! you'll never believe it until you use it. it's the best $20 you'll ever spend.

      AMAZING!!!!
      This product is amazing! We lived with a murky pool all last summer, and the pool store was telling us everything was fine. This year our pool was green when we opened it and after spending at least $400 on products from our local stores (yes, we used 2 different stores) we still had a murky pool that wouldn't stay balanced, and "silt" was constantly appearring. We were told we must need to replace our sand or our filter. We then ordered No Mor Problems and watched our pool fix itself before our ... read more eyes! Within 3 days we had a beautiful pool! Two months later, our water clarity is still brilliant! All we do is treat with this product weekly and add chlorine tabs. No more copper algeacide, super blue, shock! Give it a try!!! It's well worth it!!!

      Algae Clear
      With the ugly weather we had this summer and turning cold overnight my pool was a mess. This product helped turn my pool back to the clear inviting pool it should be. Very effective and worth every penny.

      Best Algaecide on the market
      We have used this product for at least 8 years straight now and no other product works as efficiently as this. It is costly but no other products are needed as others that need an additional product to eliminate the foam.

      long lasting
      our pool does not get covered in the winter and I love the way this lasts!

      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 ??

      Satisfied!
      Satisfied with product, price and shipping ! Will use again.

    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.
