The skimmer is not bad, the anticipated. However, it is not so, as indicated on the packaging: "insertion into the pond and there you go." Anticipation there is the assembly. For non-technical staff that is difficult, but can be the three swimmers push only overcome in the plastic device. One is afraid, directly stop the plastic noses. Then added the skimmer into the pond clean, you should previously install a weight at the bottom of the unit. Otherwise he drives namely too high, and then the thing does not work out. Of course, neither a rope nor a weight here, because then you have to tinker a bit in homework. Stupid, is also at the bottom of a check mark, which you could then attach the rope. I have the whole solved by I lashed a cable tie at the bottom, and then I have a Plasterstein secured with a dowel and a galvanized chain Brack from the truck accessories on the stone. The stone lies at the bottom of the pond, and through the chain with a hook above, you can clean the skimmer so well and he also does not float around. In addition, he now has the correct installation position. You'd give this part of the manufacturer of this chain with a plastic hook at the bottom, then the customer need only obtain a suitable weight. Would be much easier. Without this DIY it will not work properly because it simply drives too high. If even so on the box. Otherwise, it is good and I am satisfied.
