Optimized Marineland Replacement Bio-Wheel for Eclipse 2, Emperor 280B & 400B Filters - Top Quality Parts for Aquariums Review

The Bio-Rad needs to be replaced. I order 2 but one is damaged but Amazon always help us to replace it. In addition, everything works perfectly with the new bio bikes.

Many hobby shops have to order this for my aquarium and very expensive. This site saved me. It works great in my aquarium waterfall filtration. Thanks very much!

These bio wheels are perfect for my Emperor 400. The bio wheels don't usually need to be replaced as they lose good bacteria but in my case that wasn't the case in included with the used filter I bought.

Good price, good product. There is not much more to say about this. Yes, it is only 1 filter, the name is "Emperor" and "Eclipse 2" filter details, not "2 filter details". Before purchasing, please note that they cannot be replaced unless damaged. They will collect a lot of bacteria, look dirty and become much slower over time. This is exactly how they should work and means you have healthy biofiltration in your tank. Should they ever get so wet that they can no longer turn, simply rinse them…
