I just recived a penn plax sea pony from a friend who had fish like 4 years ago. Of coarse, it came with no instructions, and I don't know where she got it. I've googled it some six times and I never get anything. Has anyone even heard of this thing? I went to the penn plax site and it looks like they don't even sell them any more - just repair kits. Also this is my first time haveing an aerator, soo I don't really know what's normal, or if this thing is actually working. Also I don't even know how to instal it ect. Some body please help!
