I saw a thread on RC about using a ziplock type bag and a couple tie wraps. Supposedly works well, haven't tried it myself. I am awake right now due to overflow noise....my Maxijet return(upgrading tomorrow) must have had something blocking it's input a bit causing it to slow down. The result was a intermittent slurping noise into the overflow. Luckily moving it around a bit did the trick, can't wait to get that out of there.
