Natural Treatment for Free-Floating Aquatic Debris

Orange Oil can be used on Free-Floating Aquatic Debris (substance not attached to substrate)
Free-Floating Aquatic Debris
Suitable For Early Stages Of Build-Up: Where Water Surface Is Visible
Suitable For Moderate Build-Up: Where Water Surface Is Barely Visible
More Environmentally Friendly Than Synthetic Herbicides[3].

Control and Prevention

Orange Oil

Use Orange Oil to treat free-floating aquatic debris

  • 1L treats 500m² of surface area
  • Apply to light/medium build-up of aquatic debris on water’s surface
  • Spray on application

For best results, avoid a single heavy application. Apply several light applications over a 1 to 3 week period [4] [5-6].

Use Together With Surface Clear

Use Surface Clear to assist in keeping free-floating aquatic debris from returning

  • Apply 100mL per 100m²
  • Helps prevent further growth of free floating aquatic debris
  • Shake vigorously and tip in
  • Use after Orange Oil Treatment

Silicone-based liquid that helps reduce the re-establishment of new free floating aquatic debris on your water’s surface.

What Does Orange Oil Target?

Orange Oil targets free-floating aquatic debris on the water's surface and causes it to lose its buoyancy and sink to the bottom.
How does it work?
When the Orange Oil covers the surface of aquatic debris, it causes it to lose buoyancy and sink to the bottom.
How does it perform?
Orange Oil is a natural treatment that is soluble which makes it easier to apply [7][8]. Orange Oil is safe to use and does not have a withholding period.

How to get the most out of Orange Oil

Orange Oil is not like traditional herbicides and is best applied by someone with experience in spraying. It is important to apply Orange Oil correctly to achieve desired results.

Firstly, you must make sure Orange Oil is fit for your situation.

  • The aquatic debris must be free-floating – not attached to the substrate.
  • The density of the aquatic debris must be single layered (not overlapping)
  • The water’s surface must not be 100% covered by aquatic debris.
  • Your water body must have an average depth of >1m

You can partially remove the aquatic debris by means of physical removal to ensure you meet the parameters above.

We recommend you apply multiple treatments (minimum of 3) to effectively manage free-floating aquatic debris. You should apply Orange Oil directly to the aquatic debris and to the surrounding free space.

Ensure you use a low pressure, shower droplet spray to lightly and evenly coat the surface of the aquatic matter. If the substance moves away from you or from the force of the stream, it is too powerful.

Treatment should continue until the aquatic debris is no longer visible on the surface of your water body.

If applied correctly, we find that full applications on day 1, day 2 and day 4 are quite effective. You may need to spot spray any remaining aquatic debris. If you are not able to apply Orange Oil to all of the aquatic debris in one application, you will need to treat more frequently to ensure all of it is covered over a short period of time.

Friendly to the environment

  • Orange Oil is a natural product[2]
  • More environmentally friendly than synthetic herbicides[2]
  • Does not cause environmental pollution[2]
  • Non-persistent which means it decomposes rapidly, preventing the accumulation of compounds in soil and its subsequent influence on non-target organisms[7]
