Cloverleaf Blanket Answer is a tried-and-tested natural mineral and enzyme-based treatment that actively eliminates existing blanketweed. It works even in colder water temperatures (from 10°C and above), is safe for fish, plants, and wildlife, and does not harm biological filtration.
Cloverleaf Blanketweed Pre-Vent is designed as a follow-up treatment, applied every 2–3 weeks to keep blanketweed from returning by rebalancing your pond’s ecosystem.
Use Blanket Answer first, then start dosing with Pre-Vent two weeks later to maintain a healthy, weed-free pond year-round.
Use 1 level scoop (included) per 285 litres of pond water.
Mix powder with pond water in a watering can and spread evenly over the pond surface.
Water may turn milky temporarily — this is normal and clears in 2–5 days.
Use 10g per 1207 litres (266 gallons) every 2–3 weeks.
Or use the included scoop: 1 scoop = 3632 litres (800 gallons).
Apply dry directly to the pond or pre-mix in water.

100% safe for fish, aquatic plants, birds, and pets.
