NAC-7

[parkinsn]

I have a new NAC-7 in my set up. I can't get it set right, it just foams over. I cleaned it before use, have it sitting at 10", recommended is 9.5"-11". Its set on max but cant get it to stop foaming over.

Anyone have any thoughts? I talked to another member, same skimmer, same problem. A little further reasearch says 7" is the sweet spot. Or is just because this is a new set up with nothing to skim and it's just freaking out for the moment?

The instructions are in poor broken engrish. Is there something lost in translation that maybe the optimal hight is not 9.5"-11"?
