Crazy bubbler-help!!! Need way to fix it

[Bettaluv]

Hi, so I bought a bubbler that puts out crazy huge bubbles.
I am wondering if you DIYers could give me a quick DIY fix for this. I tried putting a lot of gravel over the bubbler, but the bubbles are huge, and it doesn't look very good at the moment. I was wondering if there was a way to minimize the size of each bubble so they are small and not so deadly for my neons!
I know that most likely the fish will avoid the bubbler, but I don't want to take ANY chances! Plus, these huge bubbles are simply not as pretty as I want them to be

When I leave a bubbler/airstone exposed on top of substrate, I get smaller bubbles. My husband puts his beneath the gravel and gets huge bubbles.
