This all-natural pond treatment clears blanket weed by depriving it of the nutrients it needs to thrive. With a handy built-in measuring chamber, the dosage is easy to control and the product easy to use.
Simply calculate the pond's volume (L x W x D (metres) x 1000 = pond volume in litres) and gently squeeze the bottle until the required amount is in the measuring chamber.
Just 10ml is needed for every 250 litres!
500ml bottle. Harmless to fish, plants and wildlife when used as directed. Use only as a pond treatment.
