How do you clean an under gravel filter? Other Pet Discussions
I just got a 3 gallon tank complete with under gravel filter (ya know, with the air pump and stuff) and it's working, but to be honest I have no idea how the filter actually does it's job and no idea how to clean it. It seems like it will be a horrible pain if I have to keep dis/re-assembling my tank each time. Also, how often should it be cleaned? Thanks so much!!
