Cloverleaf Pre-Vent Blanketweed

What Pre-Vent Does

✔ Helps prevent blanket weed regrowth

✔ Rebalances pond biology

✔ Supports beneficial bacteria populations

✔ Stabilises water after algae treatments

✔ Safe for fish, plants & filtration systems

Pre-Vent is not an algae killer — it is a preventative biological stabiliser.

When to Use

• 10–14 days after using Cloverleaf Blanket Answer

• As part of a routine 10–14 day maintenance cycle

• When water parameters fluctuate

• During active growing season (above 10°C)

Best results are achieved when used consistently.

Suggested Dosage (Clear for Compliance)

• 10g per 266 gallons (1,207 litres)

• 1 enclosed scoop treats approximately 800 gallons (3,632 litres)

The dosage may be adjusted without adverse effects.

For optimal blanket weed prevention:

• Dose every 10–14 days

• Maintain adequate oxygen levels

• Ensure proper filtration circulation

How to Apply

• Mix the required amount with pond water

• Distribute evenly across the pond surface

• Water may turn mildly cloudy

• Cloudiness usually clears within a few hours

This is a normal biological reaction.

Important Temperature Guidance

For best performance:

• Use in water temperatures above 10°C

Lower temperatures reduce bacterial activity.

Oxygen Considerations

If keeping river-type species such as:

• Sturgeon

• Orfe

• Rudd

Maintain high oxygen saturation levels before and during treatment.

Adequate aeration is recommended in all stocked ponds.

Safe for Pond Life
