Aquaclear When to use? To prevent the growth of unsightly green algae and blanket weed. Aquaclear uses a long lasting blue dye which restricts the light from the sun penetrating through the water column therefore cutting off the light source which causes algae and blanket weed to grow. Aquaclear is harmless to all other forms of life in the pond. How to use? Shake bottle well. For best results use in spring before the algae becomes too established or use Magiclear first to clarify the water. For complete control repeated additions should be made monthly as the colour fades. Water becomes a subtle blue colour and leaves your pond plants unharmed. Mix the correct dose in a clean bucket of pond water, then pour evenly around the pond. Warning: Avoid staining clothing. For use in ornamental ponds only. 250ml
