switching filters in cycled aquarium
 
Hi everyone -

When I first set up my 30g I had a 20g whisper filter on the top, and a submersible filter at the bottom of the tank.

Un
fortunately, the latter has turned out to be a piece of junk, so now I've just the 20g filter for a 30g tank ... it's taking a while but I am starting to see traces of ammonia.


So it's time to put in a stronger
filter - but of course, most of my good bacteria is in the old filter. I'm guessing I'll have to leave both running at the same time for a while. Has anybody else had to do this? How long do you usually give it before pulling the old filter out? (I'm going to use it elsewhere...)

Thanks,

Jonathan

Why not leave both running forever? That would be awesome filtration for a 30G tank :)

If not, I'd both running for a month or so, then take the insert out of the old filter, but leave it running, and then after a bit take the old filter out all together.
