Of course, a UV light filter. With our regional hardware stores such lamp cost around 80 to 90 euros, and here costs a comparable filter around 25 euros. With heavy heart, I decided to order me in spite of all the Berlan light filter. Because he can be the same as so expensive?
Definitely yes. Two days later the package was already at home. Itself very well. When unpacking you realize again how much is such a lamp. I underestimated so times to 30 cm in width which means you must, willy-nilly, they hide a bit. As can be seen in the figure has the filter via two hose connections for various sizes and a larger viewing window, which is a little more illogical at first glance. But this is used for visual inspection of whether the light is still functioning, which is not visible from the outside. Also a transparent hose connectors piece is with a red paddle inside the package, which you can check whether alone flowing water into the unit. The only problem could be the life of the bulb for me. Subjectively find a rated life of 8,000 hours, a little excessive. It is also important a stronger pond pump in order to obtain a higher Umwelzleistung. Only hung a 1.500l in the filter composite, which was then replaced by a 3.100l pump that bring much more power
To explain the performance I get from something. Some time ago I filmed with my brother the fish in the pond. Funny, I thought that we do sometimes at home. On the first day the underwater image was really dark green. A day later, it had become clear again. For reasons of curiosity, I did it again a few days later again and again as a stronger clarification was noticeable.
