Cloverleaf Blanket Answer, awarded "Best in Test" by Horticultural Magazine HDC, is a unique blend of minerals and enzymes designed to combat blanketweed. Blanketweed can spread quickly, blocking light and oxygen essential for other pond life, thus disrupting the pond's delicate eco-balance. Blanket Answer works by gently releasing bacteria into the pond water to consume excess nutrients, starving the algae. Available in three sizes, it treats ponds from 10,000 to 50,000 litres. It is 100% safe for all pond fish, plants, and biological filtration systems, and UV units do not need to be switched off. Blanket Answer can be used repeatedly, especially during summer, to tackle stubborn blanketweed problems. It begins working immediately and helps maintain filter mediums. This mineral and enzyme mix initially causes a white, milky appearance in the water, which clears within days, weakening the blanketweed by altering water chemistry. Directions for use: Use 1 level scoop (800 gram tub) for 285 litres (65 gallons). For best results, use when water temperature is above 10ºC. Mix Blanket Answer with water in a watering can and pour evenly over the pond surface. Ensure good oxygen saturation in the pond. Wash hands after use and store in dry conditions away from children.
