Thanks....I saw this video earlier in the day, and it's filtration is a little different then mind. I'm the second owner. I bought this from a doctor about 12 years ago. He had someone set it up, so he was not aware of how the filtration worked. It was a really expensive tank ($2000).....however, I got it for 480, because he just wanted to clear his storage unit. That being said, I'm going to do some more hunting over the net for my actual system or maybe I can get help here. This system used power heads.
