Duckweed is an unsightly and potentially dangerous problematic weed, and the small circular leaved plants rapidly divide to cover the entire surface area of the pond. This cuts out the light, killing any submerged aquatic plants and also disguises where water starts and ends, being potentially dangerous to wildlife, pets and children. Blagdon Duckweed Buster prevents the duckweed from taking up the nutrients it needs to grow, causing it to die back.
Remove as much duck weed as possible using a net to increase the product's rate of effectiveness.
Calculate the ponds volume. Shake the bottle well.
Remove dosage chamber cap and foil seal, squeeze bottle until chamber is filled to the required level.
Add 1 x 25ml measure for every 450 litres (100 gals) of pond water. We recommend adding Duckweed Buster to a bucket of pond water and then distribute this evenly over the ponds surface.
After 7 days add a further dose of 1 x 10ml for every 450 litres (100 gals) to a bucket of pond water and distribute this evenly over the surface.
Repeat the dose weekly until the duckweed is no longer visible.
