Cristalclear Duckweed Control gradually shifts the balance of nutrients, locking away the phosphate so that the duckweed cannot grow so much.
Crystalclear Duckweed Control should be added to the pond regularly during the growing season in order to achieve the proper control of duckweed and other nuisance aquatic plants.
Cristalclear Duckweed Control will also cause particles in the water to clump together and fall to the bottom or be removed by the filter so that the water becomes crystal clear and free from unwanted plants and algae.
Cristalclear Duckweed Control is completely safe for fish and wildlife even if applied at double the recommended dose. 250ml Treats 4550 Litres/1000 Gallons
