    In the Swim Black Algaecide Does the Job When All Others Fail

    • Black algaecide also tends to soften water
    • Highly effective, works when other treatments don’t
    • Particularly stubborn black algae blooms may require multiple treatments
    • Formula is non-clouding and non-foaming
    • Initial dosage: 16 oz. per 10,000 gallons at the onset of black spots
      • Item: # Y1400 1 qt. $19.99
      • Item: # Y1410 4 X 1 qt. $77.99

      Rated 5 out of 5 by from Great product As with any kind of algae you have to work at it! First I use pool shock which I pour liberally over the areas worst affected. 24 hrs later scrub. Then I use an entire bottle and retreat with half a bottle if necessary, the next day. This works. It was recommended by a pool guy who has been doing pools for over 35 years, not me! Just sayin!

      Rated 1 out of 5 by from This Product Did Nothing For The Black Algae I first read the instructions making sure I followed those instructions whilst applying this product to my pool. This product did absolutely nothing to the black algae. It is still clinging to the walls, unaffected by In The Swim Black Algaecide.
