NT Labs Duckweed Control – Your Solution for Nuisance Plant Build-Up in Ponds

When to Use: NT Labs Duckweed Control, also known as Cristalclear, is the ideal solution when you're dealing with a build-up of nuisance plants like duckweed in your pond. Cristalclear not only removes duckweed but also targets phosphate, the nutrient responsible for the rapid spread of these nuisance plants.

How to Use:

  1. Shake Well:

    • Ensure the product is well-shaken before use for effective application.
  2. Remove Excess Duckweed (Optional):

    • For best results, rake off as much duckweed as possible before treatment.
  3. Mix Full Dose in Bucket:

    • In a clean bucket of pond water, mix the full dose of Cristalclear.
  4. Evenly Distribute Around Pond:

    • Pour the mixed solution evenly around the pond.
  5. Double Dose (if necessary):

    • If the water is severely affected, the dose can safely be doubled without risk to fish.
  6. Weekly Application for First 2 Weeks:

    • Add to the pond every week for the first two weeks during the growing season.
  7. Biweekly Application Thereafter:

    • After the initial two weeks, apply every other week during the growing season for continued control.
  8. Minimum 6 Months Use:

    • Use Cristalclear for a minimum of six months to achieve optimum benefits.


  • Cristalclear not only targets duckweed but also helps control phosphate levels, preventing the rapid spread of nuisance plants.
