Have the compressor under the roof, where in the summer is the filter, rain securely mounted with cable ties. Is the fastest and works without problems. However, the enclosed air hose is so bad wound, which have formed kinks. And of course then flows through no air. So first of all cut the tube to the appropriate lengths and then the wrinkle smoothing with your fingers. I have additionally 15 meters hose worried because with me the way from the compressor to the pond is quite far and you should indeed spread in the pond, the six air vents. Only six vents well supplied with air when correctly not kinked hose. Have a lie, thus freezing the pond at about nine meters, even under severe freezing temperatures not to every 1.5 meters. And that's enough of my fish. However, the compressor is quite loud. With me does not bother, because the pond is far away from home. But you can at night when all is quiet to hear from some twenty meters away. That should keep in mind if you have noise-sensitive neighbors. The thing to pack in something does not make sense, because it is quite warm during operation and cooling benötigt.Bei me it is dry from the top and the sides are open, and it is still warm to the touch, even in frost. Put it in a box him he should suffer rapidly heat exhaustion at somewhat higher temperatures. For me, it comes only in the winter for use as ice-free holder in the pond. And for that it is great, especially for the price. Had he quietly he would get five stars.
