If you have another established tank you can speed things up by transferring some good bacteria. Squeeze a dirty filter pad in front of the intake, or add some used media to the new filter.
(sorry if this has already been done. I didn't see it in the thread, but could have missed it.)
I want to so this but my other tank has BBA in it and I have been battling it for a year. I have taken a lot of steps to try and make sure that this does not transfer over to the new tank, new tools, washing my hands after touching it then the other etc.... this includes beneficial bacteria from the other filer. Guess it will just be a long wait.
