With the help of UV technology, algae and bacteria can be easily and efficiently controlled. The choice of the appropriate type and model of UV lamp, depends on the situation.

UV lamps are available in a wide variety of types. We as MPF focus particularly on the most efficient UV technique: amalgam. Because this type of lamps have become very affordable in a short period of time, the energy savings achieved and the expected lamp life is such that both the fluorescent and also the standard T5 technology are becoming increasingly uninteresting.

Why amalgam instead of ordinary T5 or fluorescent lamps?
- Very high efficiency (2 to 3 times as powerful with the same power consumption)
- lamp life 13,000 - 16,000 hours (about 2x as long)
- clearer water
- UV radiation output decreases less during lifetime
- better resistance to switching the lamp on and off

UV in ponds:
The efficacy of UV on (an-)organic matter has to do with the strength of the UV radiation and the duration of that radiation. With a lamp twice as strong, the effect is the same at half the irradiation time. A lamp is normally judged by its radiation dose, which should not decrease too much during the lamp life (decrease to a maximum of 20-30%).

Algae are killed off by a relatively small radiation dose. Dead algae clump together and are then easily removed with a filter. To kill (inactivate) bacteria, a significantly higher radiation dose is required. This radiation dose is even different for each bacterial type. Often in ponds the contact time/radiation dose is so small that normally only moderate bacterial killing occurs. It is therefore important to match the desired UV capacity to your needs and circumstances.

The housing of the 40 and 80 watt amalgam has a 2" (63mm) connection. The housing of the 130 Watt amalgam is made entirely of stainless steel with a 3" (90mm) threaded connection. Even with large water volumes, the resistance of the housing is minimal.
