      I couldn't get my pool clear after dumping tons of shock and algacide in it. I bought this package and it was clear within 4 day.

      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.

      An Easy To Use Dual Use Algaecide
      I have been using "No More Problems" for several years and it works very well in keeping my inground Pool water very clear and with a sparkle. I use it between normal additions of Super Algaecide. It does a very good job & the Squirt cap allows me to apply the product right where I want it for best circulation. This is a dual purpose product as it is both an algaecide & clairifier. I add No More Problems when I notice my Pool water looking flat & I want to restore the sparkle we all strive for.

      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!!!

      8 years of perfect clarity
      I started using No Mor Problems 8 years ago in our 10,000 gallon above-ground pool and it has performed perfectly. I use 2 1/2 ounces once a week and NEVER have algae problems. The only two times I have had an algae bloom was when I skipped the once-weekly application. Each time about a week after the missed dosing, the pool became a murky green, but cleared up in a few days after starting treatment again. If you are consistent, this product is very affordable. Small, regular doses keep algae in ... read more check and the water is really sparkling clear.

      Works Great for stubborn algae
      I am very pleased with the yellow out that I bought from in the swim. Any product that I have got from in the swim has always been great service along with good dependability and yes I will recommend this to a friend.

      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.

      Great alge solver
      Tried this product because when I opened the pool was a swamp. I was shocked how fast it worked and it turned my pool from green to gray with in 20 min. Just make sure you have enough shock because you need to shock your pool 3 times. I agree with other people you also need to use a clarifier to clear it up. I will use this product again. I have recommend it to all my friends a family who have a alge problem with their pool.

      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!

      Solved our algae problems
      We had an ongoing algae problem that we couldn't seem to overcome. We would get rid of the algae for a while, but it kept coming back. Someone recommended we try Phos Free. You have to get rid of the algae first, and then start using Phos Free to prevent the algae from returning. Well, this has really helped us to keep our algae in check. Hooray for Phos Free!

      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.)

      Great Customer Service
      Similar to another poster, I followed the instructions and it clogged my DE Filter. I tried to bump it (it's not bump capable). I wound up having to completely backwash the product out. HOWEVER, I was still pegging a 1000+ p/bb on Phosphates - so I thought I'd give it another try. I called their customer service department to ask how to proceed. Not only did they offer a solution - they provided some free maintenance product after I bring the phosphates down. It always help to call! I'll try and ... read more do a follow-up post after my next batch. Therefore, if you have problems - definitely call the vendor; they appear to stand strongly behind this product.

      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.

    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.
