I tried it a couple weeks ago when I set up my DIY CO2 and the bubbles were too big, they just rushed to the surface and popped. I am using a limewood diffuser now. It gives off much smaller bubbles that slowly rise many of them completely disappearing before reaching the surface.

I used an airstone with a bell. I made the bell out of the bottom of a water bottle. This captured the CO2 and allowed for more to be absorbed in to the water.

That's what I did kind of too. I filled up a 710 ml bottle with gravel on the bottom and sunk it to the bottom of my sump. THEN I threaded my air hose into it. NOW I have a half filled bottle of CO2 dissolving gradually and excess just drifts out if it gets too full. Still, I'd use a limewood diffuser if I had one.

It doesn't even uglify the tank because it is inside my stand.

Only downside is that with that little surface area not much CO2 will be dissolving compared to the rest of the 18x36 tank and the 12x30 sump. ANYWAYs... it might work but not near as well. If you collect CO2 on a surface WITH an airstone too it will dissolve a bit better and less will be wasted.

My tank sucks now

I think this is the most effective method to disperse DIY CO2 into your planted tank:
