I am curious if this is a good idea or a bad idea. I got the idea from another poster. I took some substrate and the filter medium out of my established 10g and placed it in a plastic soup container with a hole in the top. I then put this in my 25g which has been up for 3 weeks.
I am hoping this will speed up the bacteria in the new tank? Is this a good idea or could it have negative effects?
