Pond Balance is a plant friendly formula which ensures that no harm comes to any other pond plants, fish, filtration bacteria or water-using wildlife. This treatment does not affect plants as it works by making unavailable a nutrient that is only required by filamentous algae and thus literally starves it out of existence. Treatment contains plant stimulants and so helps establish a naturally balanced pond. Pond Balance reduces blanketweed using a microbiological formulation, safely and gradually it adjusts the water chemistry of your pond, achieving a balance that effectively clears blanketweed whilst encouraging plant growth.
