Mr. Bacteria No.3 is a special biological activator designed to maintain cleanliness and ecological balance in garden ponds and fish ponds. It contains natural bacteria that actively seek out and break down organic impurities in the water and on the pond bottom. The product effectively removes sludge and turbidity from the water, decomposes organic sediments, thereby eliminating brown and murky water. It reduces algae and cyanobacteria by breaking down the nutrients that support their growth, while also reducing phosphates and chlorophyll A, contributing to long-term clean water and maintaining the ecological balance of the pond.
