Green Water Treatment

Green pond water is caused by single cell algae that are only visible when using a microscope. However, when they accumulate in large numbers, their mass increases and they become visible, creating green water. Fortunately, it is a very common problem in ponds and therefore, relatively easy to solve with a green water treatment.

Our range of bacterial green water treatment products are 100% natural, making them safe for your fish, pets and wildlife. Not only do they work effectively to clear green, murky water, but they also reduce nutrient levels in ponds to prevent green water and algae.
