The quality of a Koi pond is directly related to the installation of proper filtration equipment and quality monthly service. Koi ponds cannot be left to fend for themselves. Professional service is required to assist the filtration in reducing organic sludge and impurities that can build up and pollute the water. Blue Koi typically recommends twice a month service on any Koi pond in order to provide crystal clear and healthy water. Services provided include the following: skimming of leaves and debris, vacuuming the bottom of the pond, back-washing the filtration system, water changes, water chemistry testing, and fish inspection.
