      Nice and Clear
      First time using this combined product and was hesitant. After the first dose, the pool was noticeably clear. I was impressed and now will order these every year.

      Works fast
      When you need a quick clear up of slightly cloudy water, Ultra Clarifying Tabs will do the job in a few hours.

      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.

      I bought this at the beginning of the summer and the pool is still clear.

      This product is awesome. I have not dealt with algae since I first tried this product, 5 years ago.

      Much easier than sand
      I haven't encountered any problems by switching out my sand with the filter balls. They are a lot easier to manage (taking the sand out of the filter was a real pain) and it's too early to tell if it filters better than sand but it definitely filters as good as sand with better flow rates on my pump. They are going to be a heck of a lot easier to replace with news ones than the sand would be too. More affordable than sand, too.

      Outstanding product
      Was going to switch my sand filter to recycled glass but decided to try these first. Extremely easy to install as it took only 3 lb of these to fill my 300 lb sand filter after vacuuming out the sand and they work extremely well, my pool water has never been this crystal clean and I hardly need to backwash as often as sand. Extremely happy that I used these

      No more broken backs
      The trip from our car to the pool house is 200feet or more. Never liked carrying all those bags of heavy sand. FilterBalls was so easy to carry and less trips, I will be changing my "sand" much more often now..... and the pool water is so much cleaner

      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!

      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 ??

      patience---it does work. takes a couple days to kill it all, along with a few vacuums and brushings/if your pool is as close to the black lagoon as ours. good product.

      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.

      Top quality performer
      I use this product because it gives the kind of results I look for in algaecide.

      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!

      Worked fast
      I had a few patches of yellow algae on the plaster walls of my pool that other algaecides never quite got rid of. I brushed the affected areas, added Yellow Out and did a chlorine shock. The walls and water looked great the next morning! I was surprised the chlorine went from 10 ppm to 0 ppm overnight, but I just added a few more pounds of chlorine and now it is stable 2 ppm. The algae has not come back for two weeks! If it stays away two more, I will definitely buy Yellow Out again.

      Great product! Highly Recommended!
      I bought this product yesterday when my above swimming pool was totaly green. I had tried with the chlorine and had not results until I got yellow out. Yesterday I put half of the recipient about 9:00 pm .Today at 8:00 am my pool came out blue again! Just one thing, (make sure that you put clhorine again,because this product uses all of it ).

      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.

      InTheSwim Instructions Almost Always Lacking
      Guys, you've GOT to get it together on your opening and closing instructions. The closing instructions shown on the website page above these comments tell us to add Pool Magic first, Phosphate Remover second, Shock third. Your printed instructions with the kit say to add Shock first, WAIT a half-hour, and then add Pool Magic and the Phosphate Remover. Your online directions tell us to lower the pool level BEFORE adding anything. Anyone who does will soon realize that the pump STILL needs to be ... read more running for all of the chemicals, so lowering the water would have been a big mistake. The product is great and I really enjoy purchasing from your company, but I can't understand why you can't be clearer in these situations.

      Best pool closing kit I've ever found!
      I have used this product for several years now with great results! It comes with very specific instructions. Have had a clear pool at every spring opening. I made the mistake one year to buy a closing kit from a local pool store and had awful results at opening. Pool took forever to clear up. Learned my lesson and went back to this product. Will never use another brand again.

      Straight Forward
      Works as advertised and I have been using these for years. I find the sponge particularly worthless, but whatever, it comes with the kit.
