Agreed dylan!
I had this happen with my betta tank, the one filter was starting to break so I bought a new one and ran both of them for a month and about three days, then the one finally stopped working and I tossed it. Being left with the new one and all is well.
The only downfall for me was that it was WAY too much current for my betta and too much intake power so I had to put netting over one of the intakes to prevent his fins from getting in there and just make a spot for him to avoid a lot of the current.
Not sure what fish/tank set up you have going on.
