Get rid of the Finnex and get out the hobby for a while. There's no sense having an uninspired tank. It affects you and the health of the system if you're not that into it.

Then the bug will bite you after a while and you get to do the funnest thing in the hobby...plan and set up a new tank. And yeah, come back with something different to keep the excitement and enthusiasm up.

Best of luck to you!
