I know it sounds like a newbie question but I'm going to ask anyway. I have a 180 with 4 bass a dat a geo and pike all about 10". I have an fx5 filled with scrubbies and ceramic rings and 3 aquaclear 110's with the sponges and filter floss. I also have a spare bucket full of the rectangular sponges that go into the 110s. My question is should I just stuff the fx5 with nothing but sponges and then stuff th 3 ac 110s with nothing but scrubbies and ceramic rings for biological filtration. Water is not as clear as I know it can be right now. Tank has been running for years but I haven't achieved that crystal clear water. A sump is not an option for me.
