Now past 48 hrs with new 40 gal cube AIO running. Have turned on protein skimmer and it is running wet-filling cup up. Have dumped half full cups 5 times in 8 hrs. It is placed on partition between media box chamber and skimmer chamber. There doesn't appear to be anymore play in adjusting the height. Is this normal- will it break in to more normal function? Should I turn it off overnight to prevent over spillage?
