NT Labs Cristalclear Duckweed Control

Cristalclear Duckweed Control controls the unsightly spread of duckweed in pond water.

It works by reducing the duckweeds natural food source, thus eliminating future growth and keeping your pond water free from increased levels of duckweed.

Use Duckweed Control for a cleaner pond.

When to use:

Use with the build-up of nuisance plants such as duckweed. Cristalclear removes phosphate from the water, the nutrient responsible for the rapid spread of duckweed. Add to the pond every week for the first 2 weeks and every other week thereafter during the growing season.

Before using Cristalclear make sure you:

• Remove adsorbent filter material – carbon, zeolite etc.
• Switch off UV
• Increase Aeration
• Allow plenty of time to observe fish
• Do not mix medications
• Leave 10 days between treatments if no improvement is seen
