Blagdon Green Away is NOT a toxic algicide, it clears the pond water safely by clumping the algae together so that they sink or are removed by a filter. Green Away works with plants to create a naturally balanced pond. Harmless to filters and all species of pond fish, plants and water using wildlife.
