I just bought a 155 gallon aquarium and the guy I bought it from is using two Aquaclear 110 filters. He is only using foam as his filter medium. He says it worked ok for him. I wanted some other opinions on this matter. Aquaclear sells bags that you can fill yourself with carbon or whatever. Do I need those? I only have small aquarium experience and thought that carbon was required in the filter. I also read that carbon can be bad for live plants. Any suggestions?
