Only 3 weeks after getting my tank cycled and adding fish, my filter sounds like it's dieing (got it used). So, today I bought and added a second filter. Both of them are the hang-on-back type. I'm sure that the new one must cycle in some way as there can't be any bacteria in it. Back in Feb when I was in the process of cycling the first filter I was given some spongy media from someones canister. It's been tucked into mine since that time. When I hung the new filter today I transfered that media to it to speed the process. Is there anything else I can do? I'm thinking it shouldn't take that long since my tank has had amonia and nitrite levels at zero for weeks with 14 fish in the tank.
I'm just worried that the first filter may die before the second is ready. Any advice?
