Ok, so I've had this filter for months and months and after I forgot to take out the carbon in my filter when I was administering medicine, I replaced the carbon. Well.. after I replaced the carbon (same amount taken out) the flow is very little. The first small section with the tube overflows and very little spits out. I cant say there is ALOT of carbon in it because its the same and I even took a little out. What is going on and what should I do? I know the media (white pouch) contains beneficial bacteria and I havent added sponges or pot scrubbers yet so should I replace the pouch? Should I introduce a sponge a while THEN replace the pouch? Is the pouch even a problem? lol cant think of a reason. Thanks guys *hugs*
