One more, I also raised my Skimmer and added another pump. The one I was useong was just a average 5 to 10 gal. Airpump. And I had it wide open. But when I added another to the line, WHOA! IT REALLY TOOK OFF. SO I had to really cut back. I plan on buying a single pump from wall fart when I can. They have one for 20 to 30 gal. And one for 30 to 60
