API PondCare Accu-Clear Clarifier quickly clears hazy water to help you maintain a crystal clear freshwater pond. It works by clumping together tiny particles of dirt and silt to form larger particles that sink to the bottom. Once there, these particles can be siphoned out or trapped in the pond filter. Not only does Accu-Clear reduce cloudiness, but it also improves the efficiency of the filter. Keep your pond clean and clear with this easy-to-use additive.

Key Benefits
  • Quickly eliminates cloudy pond water that is caused by dirt, silt and floating particles.
  • Steers tiny particles into large clusters which are easily removed by the pond filter.
  • Improves the efficiency of the pond filter by keeping debris together.
  • Designed for use in freshwater ponds and comes in various sizes to best suit your pond needs.
  • Keep your freshwater pond clean and clear with this easy-to-use additive.

HAZARDS TO HUMANS: Keep out of the reach of children. For ornamental pond use only. HAZARDS TO ENVIRONMENT: Before using API Pond Accu-Clear, make certain that the pond has vigorous aeration (i.e. a fountain, waterfall, or aeration device). During hot summer months, pond water contains very little oxygen. In sunlight, algae and submerged plants produce oxygen and in some cases may be the major source of oxygen in the pond. However, submerged plants and algae consume oxygen at night. Organic matter also consumes oxygen while decomposing. When organic matter is removed by the filter or settles to the bottom of the pond, the oxygen level may drop to harmful levels if adequate aeration is not provided. Therefore, when using API Pond Accu-Clear during the warm summer months, adequate aeration is required to avoid fish death. Do not shut off pond pumps and aeration devices at night. Aeration must be provided for pond life at all times. If adequate aeration is provided, oxygen levels will not drop to harmful levels.

    My pond accumulated a lot of 'muck' while some construction was being done at my home and I couldn't run the waterfall. When I was finally able to get the water flowing again, I applied API PondCare Accu-Clear Clarifier and was amazed at how quickly it went to work to remove the sludge build up. After 3 once a week treatments, it is back to normal and looking great. What a wonderful product that will keep my pond looking good.

    It may just be MY pond

    By on

    I have a very healthy pond ((500gal), I started with 6 .29 cent fish to check it out. I have since purchased a Koi and a Shubunkin. The Koi is gigantic, and the Shubunkin is bigger. However, my pond is so healthy I have new fish on a seemingly daily basis. I have normal weather, and I have my pond cleaned 2x a year. This product used to work pretty quickly and efficiently, but it seems to not work so well anymore. It may not be the product, it may be just my pond. I continue to use it regularly though.
