That is exactly what is making the noise, I had the same issue when I hooked up a surface skimmer to my filter and it sucked in air also. I asked the same question, but everyone seemed to agree that it would be okay on the filter.
I have a few problems with bubble walls. One is that, while they look cool, they also fill your tank with little air bubbles everywhere that I think make the water less clear. Its also looks pretty unnatural, and I like my tank to look like nature, not some decoration you buy at the Sharper Image. Still though, my biggest problem is the fact that you have to get an air pump, which can be loud (at least compared to my canister filter) and require fairly frequent maintenence.
