Sorry for the delay in getting back to everyone in this thread; I never received any notice (via email) that there were any...

I tried moving the bubble bars from against the back glass up some to solve the "sucking into the filter" issue, but it just didn't work; this tank is so narrow and tall, by the time I moved the bars forward so they weren't getting sucked into the 110's intake, they were pretty much bubbling in the center of the tank...very unattractive and not what we were going for...

I have to find another way; tape really isn't advised in tank water? What about piling a mound of substrate over that section of the bar?
