It's a Seaclone. Because, any technology that uses a pun for its brand name is pretty much guaranteed to be effective and reliable.
You're lucky that yours came with some explanation of what to expect. Mine came with some pictures that were only marginally relatable to the contents of the box, and an 800 number that is open for about an hour and a half on alternat Thursdays, if the moon is full, during years when the American League wins the All-Star Game.
Given the fact that I have had chronic problems with Nitrates, and the additional fact that I have never seen anything like this in the past, I can only assume that whatever is going on is good for the tank. I'd just be interested to know what that something is. Or why it happens.
Anyway, good luck with your future protein skimming exploits!
