So I got a sw
established tank with fish about 5 or six weeks ago. it has what I think is called an all in one built in and overflow on the back instead of a sump on the bottom. The back holds the skimmer in one compartment, heater in one and bio balls in the other 2. I've been told by lfs
to slowly start removing bio balls and I've read many different things about this and actually started removing some each week during water changes but I thought I'd get some of your opinions on the subject. Do I leave the bio balls in or take them out?
