Nop skimmer is gonna starat right off and work like it should. The seaclown as well as any othe rksimmer needs a breaking period to wash off all the mold release agents etc used duruing manufacture, so don;t get too upset with it until its run for a week or so.....BUT its still a seaclone, and they do not carry the best reputation for working. Those that do work usually always require constant fiddling with and have to be kept really clean, and then they are borderline at that. I wont go to the extent and say they are junk, as they do work, with constant adjustments and fiddling with them, but they do produce skim. They just are not as efficieint or easy keepers as other skimmers are. For a few bucks more yu could have had a coralife super skimmer that would indeed do the job, and do it quietly, without the need to continually fiddle with it.....There are mods that folks have done to the seaclone to make it better, but for what they cost you should not have to mod a thing for it to work properly witout constant fiddling.
