Whisper Filter
I have been reading on these forums that whisper filters are not very good. Some people recommend placing bioballs or ceramic in the filter. I have 2 30 gallon tanks both with whisper filters. They have the little white bag that you put the charcoal in. I was wondering what I could put in the bag or filter to make it better or if I should take one of my filters back, I just purchased it, and get a new one?
If I should put anything in what would I put and how would I go about doing this?
