FAQs

Is this product safe for my fish?

Yes, it is 100% natural and safe for all pond fish, including sensitive species like Sturgeon, Orfe, and Rudd, provided oxygen levels are maintained.

Can I use this to kill an existing heavy blanketweed infestation?

No, this is a preventative product. You should first use Cloverleaf Blanket Answer to clear an existing bloom before using Pre-Vent to stop it from returning.

How often should I apply the treatment?

For best results, apply every 10-14 days to keep the pond balanced and prevent weed growth.

What should I do if my pond water is below 10°C?

Do not apply the product. Wait until the water temperature rises above 10°C to ensure the enzymes are effective.

Will this harm my water lilies or other plants?

No, the formula is safe for all aquatic plants.

How much does one scoop treat?

The enclosed scoop treats approximately 3,632 litres (800 gallons).

Troubleshooting

Water remains cloudy after 24 hours

This is usually caused by excessive organic load or poor circulation. Ensure your filter is clean and check that your pump is providing adequate turnover.

Blanketweed is returning despite regular dosing

Verify that your pond water temperature is above 10°C and ensure you are strictly adhering to the 10-14 day maintenance interval.

Difficult to distribute powder evenly

Mix the powder thoroughly in a large bucket of pond water first to create a slurry, then pour that mixture across the surface of the pond.

Setup, Compatibility & Care

For accurate dosing, use the provided scoop. The dosage rate is 10g per 1,207 litres (266 gallons) of water.
