Hey again. I had tried to find that aluminum duct tape, but gave up and had to go with the old fashioned stuff. I also have the check valves, they were cheap and I figured they would save me a headache if water backed up. The only other thing that is different in my setup is I have 2x12" airstones. I guess all that really means is that I'm spreading out the bubbles a little more, not that I'm pushing more air (I'm pretty sure we're using the same type of pump).
