Upgrade Your MarineLand with Advanced Bio Wheel Bearing System - Get Top-Quality Replacement Parts Review

Product works as intended, no problems. However, the price is astronomical for the two small pieces of plastic you get. My next aquarium will look very different and I'm sure I'll find equipment that avoids expensive replacement parts.

I'm so glad I can buy these little things. When cleaning my tank and filtration system they get lost so easily between the rocks at the bottom of my tank. Thanks to Revain for helping keep this item handy.

The bio wheels on my Marineland 350 started to crawl. Upon closer inspection, it turned out that due to friction, the bearings were actually lapped and the wheels were binding. These replacement bearings fit perfectly and now the wheels spin like new!

The tabs themselves were fine. The filter cannot be repaired. Replaced the tabs which were clearly worn, the wheels still turned poorly. Replaced wheels, much worse than the original. Then the impellers wore out. The impeller costs $10 less than the entire filter. Over the years this company has gotten cheaper and of terrible quality. Buy another filter
