I've found such fish bubblers on ebay, despite warnings they fall apart in  
cucl a small one i tested didn't.
The ones on ebay are 30cm long green ones and are only 2eur each. will get  
'em.

I see no way getting big bubbles that are not in streaks, one would need a  
mighty pump to have holes so closely spaced with large diameter.
