Biological Inhibitor of Green Water, Alternative approach to algae control

Controls green water algae in water gardens containing live plants and fish

API PondCare Microbial Algae Clean is a biological treatment designed to control green water algae (Chlorella) in ornamental ponds and water gardens containing live plants and fish.

It uses beneficial bacteria to help reduce green water algae while also breaking down organic sludge and debris that can contribute to pond odours and poor water conditions. The bacteria also help establish and maintain the pond's biological filtration, supporting a healthier environment for fish.

API PondCare Microbial Algae Clean is designed for use in synthetically-lined ornamental ponds and water gardens where all water is contained and there is no outflow.

It can be used in ponds containing live plants and fish when used according to the label directions.

Wonderworld Tip

Green water can be frustrating, especially when the pond looks perfectly healthy one day and turns pea-green the next! Along with treating the algae, it's worth looking at sunlight, nutrient levels, feeding and biological filtration, as these can all contribute to green water.
