    Destroy Unsightly Algae with Yellow Out Pool Products

    Don't let algae sideline your enjoyment of your pool. Yellow Out algae problem solver is the premier product for solving algae-related issues in swimming pools. This powerful product is simple to use, requiring no brushing. It will bust through even the most stubborn of algae and revitalize the look and feel of your pool.

    Yellow Out is also non-toxic and can be used on all pool surfaces, including vinyl liners. If you have a salt generator, that’s no problem either as Yellow Out is incredibly versatile. Once you follow the instructions for balancing your pool and add the recommended dosage of Yellow Out, add a shock treatment five minutes later and then run your pump and filter for 24 hours. All you have to do next is dive into your refreshed, algae-free pool.

      INSTRUCTIONS

      Initial Application

      1. (a) NEVER pre-mix YELLOW OUT with chlorine (b) NEVER add YELLOW OUT to a bucket or pail (c) NEVER vacuum pool immediately after application (d) NEVER add to skimmer basket or filter suction line! Very strong reaction with chlorine can occur if not mixed in pool. Circulate pool water through filter and, for best results, brush pool well before beginning.
      2. SHAKE WELL TO BREAK UP THE LUMPS (product lumping in transit is normal). Adjust chemical balance to: pH > 7.8, alkalinity 80 -120 ppm, cyanuric acid 25 - 75 ppm and chlorine level 2 - 2.5 ppm.
      3. ADD DIRECTLY TO POOL 2 POUNDS YELLOW OUT per 15,000 gallons water. Spread half of it along the perimeter of the pool, starting where the algae are the thickest. Concentrate the rest directly over the problem areas. Never add more than is recommended.
      4. WAIT 5 MINUTES, THEN ADD DIRECTLY TO POOL 2 pounds powdered chlorine (or equal) per 15,000 gallons water.
      5. CIRCULATE POOL WATER with filtration continuously for 24 hours using only the main drain if possible. Repeat step 4, adding additional chlorine after 12 and 24 hours.
      6. Return equipment and chemical balance to normal after clean up.

      Rated 5 out of 5 by from Awesome My pool had algae for over a month and I spent well over $500 trying to clear it up. I put this in it and all the algae clumps together and then you vacuum to waste. Just wish I had tried this sooner.

      Rated 5 out of 5 by from Amazing! This stuff is amazing. Tried many other products and this works better than anything else. It is fast and does the job when nothing else works.

      Rated 5 out of 5 by from 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.

      Rated 5 out of 5 by from Something Finally Works!! We had tried everything the pool company suggested and nothing had worked. We were tired of spending more money but our pool was GREEN! I added 3 lbs of yellow out and 2 bags of shock to our pool and 36 hours later, it was beautiful blue again! I will definitely keep this on hand!!

      Rated 5 out of 5 by from 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.
