The whispy white stuff appears to be harmless.  Snails that find their way
into the filter compartment seem to eat the stuff.  You can take that hard
plastic tubing and carefully heat it with a small heat gun.  Then either pull
it or put a twist or bend in it.  The constriction will give you smaller and
more bubbles.  Make sure that you haven't completely closed off the opening,
