FAQDue 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. Both lamp changing and quartz tube cleaning instructions are clearly described in the Owner Manual for each unit, which can be viewed in the documents section of this website. These two maintenance items require very little time to complete and do not require any special tools or equipment to accomplish. |
