I thought the same too. I wondered if the plastic balls were to disrupt the flow, and the ceramics to hold bacteria. For some reason i cant imagine the plastic balls to have more surface area.Interestingly, the manual says that ceramic rings are to disrupt the flow of the water NOT to act as biological filtration.
Was there a noticeable difference in noise once it was replaced? I think air might have been the problem with mine. The tubing is annoying too, very stiff.hellohefalump said:I've had mine a while now. I've got used to the noise, and tetratec were very good about replacing the hose adaptor, which was letting a lot of air in. The air problem appears to be fixed now (still early days, replaced it yesterday!).
Yeh that pretty daft. The eheim 2080 I have it the same size if not bigger, and that has handles and wheels.My biggest gripe with it though, is it was very difficult to get out of the cupboard, full. It's extremely heavy with no obvious place to hold onto, and in the end I slid it out. After taking the media out, I emptied the water out with a jug until I could lift it.
