Good filtering function

The good filter function of Oasis 57377 16000 BioSmart allowed in conjunction with the pump Pontec 50855 that the water quality in my fish pond (about 5000 liters) has greatly improved within 14 days. Thanks to the UV-device is not affected by algae more noticeable, and a view on to the bottom of the pond is possible.

I had no satisfactory water quality with smaller filters and pumps weaker. In this respect a recommended combination. To save energy, I will continue to halve the life of the investment of approximately 12 hours to about 6 hours due to the current quality of the water.
