Due to the fairly good reviews here and the absolutely unbeatable price / Leistungsverhältinisses I then decided to use this filter set, in which everything is possible, what is needed, and at a very good price.
In theory, as unfortunately has been lacking with the first delivery of the hose connection pipe for the pump and the hose itself had a hole.
A quick call to Amazon and I was totally uncomplicated replaced the entire pump, the second shipment was then fine.
At first I was a little disappointed because I expected due to the recession here is that the pond would be clear again in a few days, unfortunately it was not like that. It took me already 4 - 5 weeks now the water is clear again, however, I see to the bottom and the fish seem to feel much more comfortable as well.
All in all I can only recommend the product - something you have to have patience, while waiting for the success. If you then also buys from a dealer, the case of damaged or faulty equipment (which lt. Reviews but often occur seems) reacts quickly and easily can actually hardly anything to go wrong.
