Do Koi Pond Installations Require Any Special UV System Maintenance ?
Due to the increased nitrogen in the pond water caused by the fish population, the quartz tube is more susceptible to film build-up than in other installations. Thus, it is recommended that to obtain optimal operation of the UV System, that the quartz tube inside the UV vessel be cleaned every four months instead of the recommended bi-annual cleaning recommended for other installations. Also, like all Delta UV Systems, the UV Lamp must be changed each year as the bulb life of 9000 hours is reached over that time period.
