Don't count on it. But even if it did, you still want the diffuser on it to
keep your fish from migrating from pond to veggie filter and back! Talk
about developing some muscles, swimming against the current on the way back

I have a BD installed but I did not install the diffuser yet, so I have
just
a raw pipe sticking up. I do not see any evidence of a vortex being
created
in the water. Is it possible that the combination of 4'' pipe and size of
my
pipe negates my need for a diffuser?
