I have previously used air pump and air curtain. I was happy with this set up but the pump was noisy so i was looking for a quieter option.
I bought an internal air pump that sits inside the tank and creates a colum of air bubbles. Its quiet but it creates alot of tiny bubbles throughout the tank instead of the curtain of nice bubbles i'm used to.
After being on for a few second the whole tank is full of tiny bubbles. I only have it on for a couple of minutes at a time as i'm scared the bubbles can be harmful to the fish.
