      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.

      My pool suffered with stains for years. The time we spent sweeping it to get rid of the stains was in vain. I thought that eventually we would have to spent big bucks to have it re-plastered. I read reviews of this product and thought I'd give it a try. I ordered it and In The Swim shipped it out fast. Poured it in the pool, turned the pump on, and I couldn't believe my eyes. The next day when I looked at the pool it was clear, bright as the day it was built. No stains. Dead algae at the ... read more bottom...yes. But no stains! Ran the pumps again to clean up the dead algae and there it was. A beautiful pool with white bottom and sides. This stuff works.

      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!!!

      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.

      No Mor Money
      The recommended dosage is quite costly to keep up with and will require you to go thru several bottles in a season. It's active ingredient: ~40% sodium bromide...not sure why they can't tell you that in the specs, other than it's not all that special. I ran into problems with this stuff - the bottle doesn't really address if you have algae - I had to resort to a quat to take care of the problem. So, if you have a perfect pool and never get algae, this is for you. But I would highly recommend ... read more using a quat or copper-based algaecide in addition to or instead of this product. This is not the panacea it (and most reviewers) claim it to be!

      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!!!

      Fixed a problem
      We have struggled to keep our chlorine level up all summer. Despite little sign of black algaecide, we decided to try treating it anyway. Amazingly, our chlorine level is now staying at the recommended level and we hope our problem is solved.

      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.

      Keep fighting it
      Black algae is a scourge of old pools. It gets in the gunnite and there is basically nothing you can do. You just have to keep pouring in the chemicals and watching your pool laugh at you. I am here to tell you no black algeacide works to eradicate. They all work to help control. Some are a little better than others. This one is fine. I have not seen a big difference in the super expensive black algaecides that are sold. It's all about how much active product is in the bottle. If you have black ... read more algae in your pool, my sympathies, just learn to live with it and be so happy on those days when your water looks clear and sparkling and you beging to kid yourself that it's over. It's not. Keep a bottle of algaecide close at hand at all times. Good luck!

      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.

      I used this in combination with the Algaecide 60 plus & had wonderful results! We have been combatting algae all summer & the pool stores were out of solutions! I put this & the Algaecide 60 in and within one day had a beautiful sparkly pool. It did cause a massive need for chlorine all of a sudden. We usually check our combined chlorine levels as well as free chlorine & our tests indicated that we needed chlorine levels of around 50 to burn everything out! After a ton of shock, we finally ... read more started seeing some free chlorine coming back! Also, our ph dropped at some point, so be prepared with some bicarb :-) However, all of our levels are back to normal & our pool is beautiful!

      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.

      Great Product - Needed more shock
      The Algae Attack Pool Chemical Value Pack was fantastic. It was able to kill the algae in our pool. We just bought a house that came with a pool. The previous owners didn't take care of the pool so it was EXTREMELY DARK GREEN! This product worked great in getting it clean! (It didn't get the pool 100% clean, but it was so horrible.) Definitely recommend the product! Our gunite pool has never been happier!

      Wow Really works
      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.

    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.
