Without tinkered fixing the skimmer moves from one to the other corner. That's good, because this whole water surface is sucked, but the burst of water and the air bubbles that are directed downward, the ground near the shore dig completely on. The pond liner was algae-free in no time at the shore, muddy the water turbid and ugly.
So I, like other writers tinkered also an attachment. Now skimmt the part on the spot, turns nervously in a circle, thus cleans the surface but only in a Umreis of about 1 m2. The skimmer not even make the smallest leaves, which are removed about two feet, suck. At a water depth of 130 cm, the beam is still so strong that the reason stirred up and the water becomes cloudy.
Cleaning is also very troublesome. Larger particles, if the Simmer really times with luck what feeds remain in the plastic sieve. Smaller particles get caught in the blue sponge, when removing the water but the mud evaporates again. So the skimmer for cleaning must be lifted completely out of the water, which in turn can not be to do with the basic anchoring.
Conclusion: A toy, which like the fish due to air emissions, but otherwise useless. Will probably repel the skimmer with a lot of loss in eBay again.
The delivery service was perfect, the product is a flop.
