      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.

      Algae clear
      It was weird, but welcome that it is not blue. That stuff stains and so far our pool is crystal clear.

      Does exactly what it says!!
      Bought this product while looking to buy a pool cover. My pool looked like a green swamp after a long period of rain and warm weather. Needless to say that I'm a firm believer in the saying that anything to good to be true usually is. All I have to say is WOW!! This stuff is fantastic. Poured the product around the edge of the pool and in 2 days water was crystal clear. No scrubbing needed.Worked so well I immediately ordered another container! Get this, you won't be disappointed!!

      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.

      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.

      Saved Me Mega Money and Time
      Two years ago....after being gone for three weeks (and having some attention by my house sitter) my pool got totally out of control. Mega algae bloom. After much effort.......I was told that by pool maintenance pros that I would have to replace the water and possibly the sand in the filter. Replacing the water did not solve the problem.....yellow algae started to return and I was facing about $1000 to change out the sand in my filter. Fortunately No Mor Problems was recommended. I have not had a ... read more problem since. Very good product....use it weekly......outstanding!!

      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.

      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!

      This is th e best stuff I have ever used I love it
      I love yellow out I will never buy anything else. This is the only stuff that you can just put it in and let it go. Last summer my pool had really green water ,I went to the pool place in my area they gave me $150.00 worth of pool stuff, they told me to put it in and it would be clear in 3 days. I did this and still a green pool. I got this yellow out put it in and in 8 hours my pool was clear, I can not say enough good things about this product.

      Finaly something that works
      We (or a friend) brought mustard algae from the lake. I spent hundreds of dollars on other chemicals in the past 3 years to get reed of the algae but it kept coming back a couple times per year, especially when we forgot to run the Polaris for a week. I tried every algaecide I could find in the stores and pool supplies companies. That's when I sent an email to ask what product would work best for my well water, salt system inground vinyl pool. Yellow out is just fantastic, It killed mustard ... read more algae overnight like nothing I tried before, with less than 2 pounds of it! Hopefully it is gone for good! Untill somebody brings some from the lake again. Tip: Make sure you ask anybody ready to swim in your pool if they used their bathing suit in a pond, lake, river, sea etc... and if they washed their suit since. That's how we ended up with mustard algae in the first place. Great product, Thanks.

      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.
    2. 9 years ago
      This algaecide worked well and took care of my black algae.

      It works well!
      Have used this in the past and it works well enough to purchase again. It devastates any returning black algae. I had it speckled all over when I went to open my pool 2 years ago. Nothing worked till this. I did scrub all over once I put it in the first time. The algae let go and was swept up and away.

      Not Perfect but Very Good
      My water was crystal clear, but I did have algae growth on bottom. I just couldn't get it to clean up when we opened. After a water test we found the phosphorus too high, so it looks like we had other issues. All is crystal clear now!

      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.
