Yes, i have the same fear with the fly screen.
In the meanwhile i made two more holes, making it more even.
but 7 holes is the max. number the pump will do, more and some holes will
stop bubbling.

It is fine now however, and i'm satisfied with it right now. but that
won't last i guess.
The etching is much faster now.
