Pre-Vent by Cloverleaf is a water treatment designed to help prevent the return of blanketweed following an initial clear-out with Cloverleaf Blanket Answer. This easy-to-use formula contains a bacterial culture that supports the natural balance of your pond’s ecosystem, where other commercial treatments may fall short. It’s completely safe for pond fish, plants, and filtration systems, making it a reliable part of ongoing maintenance.

Key Features:

• Prevents the reappearance of blanketweed after initial treatment
• Used 10–14 days after Cloverleaf Blanket Answer for best results
• Supports pond balance with natural bacteria cultures
• Safe for fish (including sturgeon, orfe and rudd), plants, and filters
• Suitable for regular use with flexible dosage and no risk of overdosing
• Quick-dissolving powder that disperses easily across the pond surface
• Best applied in water temperatures above 10°C
• May temporarily cloud the water, which typically clears within hours

For the best results and ongoing pond health, use Pre-Vent alongside Cloverleaf Absolute Pond Pearls. Together, they help break down organic waste, promote beneficial bacteria growth, and keep the pond environment in good condition.
