Bubbles out of the top of sponge filter

[Zac]

 So I have 2 medium aquarium co-op sponge filters with nano air pumps and a ziss air stone. Every 3 seconds, a single bubbles comes out of the same spot in each of them. I’m not worried about it, but it’s mildly annoying lol. The airline tubes on the inside are almost as short as they can be (maybe an inch or so long). The sponge filters are sitting straight (at least it looks like it). And I don’t believe a nano air pump would really push too much air through a sponge filter. Any other suggestions on how I can fix it? I’ve tried loosening and tightening the air stones. They’re on the tighter side right now but not overly tight

How old is the filter? Sponge filters sometimes do this when they clogged. I've had it happen when they get shifted and are no longer level and the air follows the path of least resistance.

They’re brand new. Been in the tank maybe a few days at most. Only thing in the tank is wood, slate, and sand
