Maintenance ultraviolet light sterilizers (uv pond filters) needed once per year.

Ultraviolet light pond clarifiers or sterilizers will give you guaranteed clear water so long as the ultraviolet light sterilizers source is changed once per year to ensure good algae control. The quartz tube should also be cleaned annually. Pond algae control using uv sterilizer gives clear water. Pond algae control using uv sterilizers pond lights is simple and absolute. However the uv sterilizers lamp has a finite life of around 8,000 hours. After this length of operating time uv pond filters as they are sometimes called stop radiating ultraviolet light.

Then it is time to change the lamp. At the same time check the quartz tube any build up of algae or pond salts should be removed by soaking the tube in dilute acid for a couple of hours.

UV sterilizers maintenance is really as simple as that.

If you find that your pond starts to go green before the year is up then check the quartz tube of the ultraviolet light sterilizer. Any build up of foreign matter on this surface will lower the efficiency of the ultraviolet light sterilizers very significantly.

You must change the uv sterilizers lamp to maintain pond algae control every year at least and perhaps. The lamp life is about 8,000 hours.

It is best to run uv sterilizers  24 hours per day but this is not critical.

Practical Algae Control involves using uv light ... chemicals are out. They are expensive of limited use and create other problems. View your pond as an ecosystem, one requiring you to manage it to maintain proper balance. Fish ponds without adequate plantings are most susceptible to algae bloom problems. These ponds are usually well stocked with overfed fish. The absence of aquatic plants eliminates competition with algae for available nutrients in the pond water.

Practical fish stocking densities and feeding must be managed closely. UV sterilization is a proven method for controlling waterborne algae. Combining sterilization with adequate mechanical filtration and operating the two properly is most effective in eliminating algae blooms and maintaining clear water. This combination will not, however, control nitrogen or carbon dioxide levels. Practical fish stocking densities and responsible feeding, along with routine filter and UV sterilizer maintenance play a big part in achieving a balanced system. Partial water changes (approximately 10 percent of the pond volume weekly with non-chlorinated water) will aid in diluting nutrients. Filamentous algae may grow and will benefit the pond by consuming nutrients and carbon dioxide. Responsible fish feeding will encourage the fish to graze on the filamentous algae, which is good in their diet. Filamentous algae may also be harvested and used as a fertilizer in gardens; remove it by hand or with a long bristle brush.
