This koi pond has been set up for years the sisters’ backyard, but without proper maintenance and care. The algae bloomed and debris built up on the bottom. It to began affect the koi and you could hardly see them. They chose D & S Koi Ponds to refurbish this pond because of their great reputation! After completing a full pond cleaning, and installing a new PondMAX filter, the pond was given a whole new life. With proper maintenance of the filter and equipment, ponds can look as good as the first day it was installed, always.
