just got my peg leg skimmer up and running yesterday and after an hour of a vinegar bath its already producing today. i think its def gonna blow my nac7 cone out of the water and in the same price range gonna def go for another one for one of my other tanks. i also go a ato from them, its a little harder to set your levels than the float switch style it took an adjusting or 2 but its workn as good as my reef fanatic and better than my jbj and it comes with a magnet not suction cups
