Pond balance clears blanket weed.
It is a unique non-algicide plant friendly formula ensuring that no harm comes to any other pond plants, fish, filtration bacteria or water using wildlife.
It does not effect plants because it works by making unavailable a nutrient that is only required by filamentous algae and therefore starves it out of existence. Also contains plant stimulants and so helps establish a naturally balanced pond.
This size treats a pond up to 40914L (9000G)
= 13638 litres (3000 gallons) three times.
