I got reef octopus extreme 160 used couple weeks ago, but I never owned a skimmer this big before, I had a small cube tank before I upgraded to 57 couple weeks ago. I got his skimmer along with it. My question is, first I was not producing enough bubbles for it to come out to the skimming cup, so couple hours ago, i took the skimmer out and hosed it down with water, cleaned all the junk and stuff. Now when I installed it its overflowing with water. And I can't find manuel for this product anywhere. Any idea what to do?
